Watch: Scandals from Sunak's 100 days as PM
Yesterday marked Rishi Sunak's 100th day as prime minister.
From Suella Braverman to Nadhim Zahawi, a series of scandals have plagued the PM.
Watch below as political correspondent Amanda Akass goes through what has happened since Mr Sunak took office in October.
Who is striking in 2023, when and why
Tuesday saw the UK's biggest day of industrial action in more than a decade as teachers, university staff, train drivers, civil servants, bus drivers and security guards all went on strike.
But this is far from the end of the industrial action, with train drivers walking out today and tens of thousands of workers set to stage further walk outs in the coming weeks and months.

Union boss warns rail strikes could last until 2026
Strikes by train drivers could continue for another three years, a union boss has warned.
Train driver members of Aslef and the Rail, Maritime and Transport union (RMT) have walked out today in a long-running dispute over pay and conditions.
This has left large parts of the country with no services, as operators such as Avanti West Coast, CrossCountry, Northern and Southern are not running any trains.
Aslef general secretary Mick Whelan told LBC radio that train drivers have not had a pay rise in four years.
Asked how much longer union members can financially sustain striking, he said: "I think we're in this for the long haul. How long is a piece of string?
"If we don't get a pay rise for four years will it be five, will it be six, will it be seven?
"Will it be stupid to stop this now then restart it some time in the future, because you'd lose any impetus that you've gained?"
He told LBC that Aslef has made no progress in negotiations with the Rail Delivery Group, which represents train operators, during six months of strikes.
Asked about the prospect of a deal being struck during further talks on 7 February, he said: "We want a resolution. My people don't want to be losing money, they don't want to be standing out in the cold."

In case you missed it...Sky News obtained the seating plan for the Tory 1922 Committee centenary dinner
Happy birthday to the most important closed shop in British politics.
The 1922 Committee - an exclusive club comprising all backbench Conservative MPs renowned for defenestrating British prime ministers - is 100 years old.
There might not seem to be much to celebrate right now in Tory politics, yet almost all of them, along with partners, peers, ex MPs - and the odd donor and strategist - were shipped off to the Hurlingham Club in West London for a black tie dinner.
London Playbook reported an evening of Champagne, seared beef fillet and quips about men in grey suits and normally that would be the limit of transparency of such an event.
Now Sky News has obtained the seating plan - the full guide to who was invited, and - more importantly - who was placed where.
Now you too can find just how importantly the 1922 executive rank your MP by who they were placed alongside - there were 50 tables for the great, the good and the rest.
Of course, some guests may not have turned up, and Machiavellis - of which the 1922 has a few - may have moved around some of the name tags. But this is a good guide to last night's plan.
Rishi Sunak was at table four, sat alongside the chef d'orchestre for the evening Sir Graham Brady.
Also on table four was Sir Lynton Crosby, whose protege Isaac Levido is running the Tory election campaign, and veteran Conservative donor, philanthropist and author Lord Ashcroft.
Former 1922 chairman Archie Hamilton was also there, as was Lord Strathclyde a former leader of the Lords.
There was no apparent sign of deputy prime minister and man in the news Dominic Raab nor of recently departed cabinet minister Nadhim Zahawi. Boris Johnson is currently in the United States.
One interesting name is Tory donor Maurizio Bragagni on table six.
Mr Bragagni, who has given £650,000 to the party, said Sharia law was the "de facto law" in some English towns and cities, in an online article and described London as "worse than any African metropolis".
Last year a Tory spokesman said the party "in no way whatsoever condones these unacceptable comments".
Table six also lists ex-leader Lord Howard and 1922 exec member Sir Geoffrey Clifton-Brown.
Another headaches looms for Sunak as BBC chair and former adviser set to be grilled by MPs
The next step in the saga of Richard Sharp's appointment as BBC chairman is set to take place on Tuesday.
It comes following reports almost a fortnight ago that Mr Sharp helped facilitate a loan for Boris Johnson worth £800,000 before being appointed to the role at the broadcaster.
The controversy concerns events before Rishi Sunak became prime minister.
Mr Sharp was an adviser to Mr Sunak when he was chancellor during the COVID pandemic and the par worked together at Goldman Sachs in the early 2000s:
Now, the chair is set to be quizzed by theDigital, Culture, Media and Sport Committee next week.
Announcing the evidence session, the committee said: "The DCMS Committee will question BBC Chair Richard Sharp following media reports about his appointment."
Mr Sharp had to appear before the committee before getting appointed, and the cross-party nature of the panel has been used by his defenders to counter claims of a conflict of interest.
But speaking last week, the SNP's John Nicolson - who sits on the committee - said the MPs did not have "all the facts".
Simon Case, the embattled cabinet secretary, once again crops up in the narrative.
Mr Sharp said he and Mr Case had a "discussion" about "avoiding conflict, and the perception of conflict".
The pair "had the judgment that I'd avoided a conflict or a perception of conflict," The BBC chair said.
Mr Sharp and Mr Johnson have denied they made financial arrangements together.
Sunak's first 100 days: What polling tells us about how the public views PM's performance
by Alan McGuinness, digital politics assistant editor
While they are liable to change and provide a snapshot of sentiment at one particular time, opinion polls are a useful tool when judging the performance of a prime minister.
This is especially the case when you look at the trends over time.
So what do the polls from Rishi Sunak's first 100 days tell us about how he is perceived to have fared?
In short, while there have been steps in the right direction, the PM is facing a big challenge to ensure he is still in office after the next general election due in 2025.
When it comes to the overall performance of the Conservatives, the party has recovered its standing in the polls somewhat, having seen its numbers fall heavily in the wake of Liz Truss' mini-budget that saw her premiership cut short after just 45 days.
But Labour still retains a healthy poll lead and it seems the party is on course to win the next election.
The government's net approval rating has also increased, but two of Mr Sunak's more recent predecessors were performing better on this score after their first 100 days:
And what of the PM's own approval rating?
He may have outlasted his most recent predecessor, but Mr Sunak knows he is going to have to engineer some turnaround to ensure he lasts as long as the likes of Boris Johnson and Theresa May.
Sunak's survived in Number 10 twice as long as his predecessor - but it's not been a smooth ride
Rishi Sunak may have already outlasted Liz Truss by quite a margin, but the 100 days he's been in office have not been short of scandals.
Our political correspondent Amanda Akasslooks back at the rockier moments of PM's tenure so far:
From Zahawi and Raab to seatbelt gaffe - the U-turns and scandals of Sunak's first months as PM
Rishi Sunak's first three months as prime minister have been far from plain sailing.
Significant storm clouds are hanging over the government as the prime minister looks to overturnLabour's commanding lead in the polls.
DespiteMr Sunaktrying to distance himself from the turbulent premiership ofBoris Johnson, rows over propriety and standards have continued.
Here, Sky News looks at the scandals and U-turns during his time as PM - includinghis sacking of Tory chairman Nadhim Zahawi:
Number 10's response to Raab bullying allegations bears striking similarities to its handling of the Zahawi affair
How much was known about accusations of bullying by Dominic Raab before he was reappointed to the cabinet in October?
The formal investigation into the deputy prime minister hasn't even finished, but questions are already landing at Rishi Sunak's door about whether flags were raised before he brought his political ally back to the top of government.
Today, the Times newspaper reports that the most senior civil servant in Westminster, Simon Case, was informed of a written complaint made against Mr Raab months before his appointment.
That comes after Sky News reported that Rishi Sunak was warned informally about his conduct last summer.
Dominic Raab has always denied any inappropriate behaviour and says he's confident of being cleared.
The response from Number 10 bears striking similarities to the handling of the Nadhim Zahawi affair.
"Due process" are once again the watch words, with the phrasing used by the prime minister's team carefully choreographed to pointedly emphasise that no "formal" complaints had been raised in the appointments process.
The political risk is that as the Raab investigation trudges on, more stories of this kind dribble out and the topic of sleaze is kept in the minds of the public.
One way to solve this would be for the deputy prime minister to step back from frontline duties while the inquiry is ongoing, as opposition parties have suggested.
This seems unlikely given the forthright defence offered by Mr Raab though, as it may suggest something of an admission of guilt.
It's another headache for a prime minister who came into power promising a new emphasis on integrity and accountability.
Beth Rigby: Little warm glow around Sunak's leadership - but supporters see 'very narrow path' to victory in the next election
The first 100 days of Rishi Sunak's premiership are done - a yardstick that his predecessor Liz Truss never even reached, while Boris Johnson found himself utterly consumed with firefighting a pandemic.
Mr Sunak can take some comfort in the fact he's made it this far without a full-blown leadership crisis or an external global event that has blown his plan for government wildly off course.
But it would be hard too for the prime minister, in good faith, to say his first 100 days have been a success, writes our political editor.
However, supporters of the PM see a "very narrow path" if he can deliver on his key priorities.
