Wales' First Minister has criticised the behaviour of protesters who surrounded Sir Keir Starmer as he left Parliament.
The Labour leader was escorted into a police car outside Parliament after protesters surrounded him.
They could be heard repeatedly shouting "traitor", while criticising the Labour leader for supporting Covid vaccinations and not "opposing the government". Some protesters were holding signs opposing mandatory vaccinations and restrictions to curb the spread of Covid.
There were also shouts about attacks on journalists, such as Wikileaks founder Julian Assange, and untrue claims about protecting paedophiles. Last week, under-fire Prime Minister Boris Johnson made unfounded claims about Sir Keir.
Wales' First Minister Mr Drakeford tweeted: "Disgraceful scenes outside the UK Parliament this evening. We have a duty to conduct political debate responsibly. Words and actions should never incite intimidation. Our democracy depends on decency and respect."
Downing Street has refuted claims that comments by Mr Johnson had inflamed the situation.
Mr Johnson made comments in Parliament last week when he was responding to the publication of the Sue Gray report. He said Sir Keir was "a former director of public prosecutions – although he spent most of his time prosecuting journalists and failing to prosecute Savile, as far as I can make out", the prime minister alleged.
The claim is false because, although Sir Keir was the head of the Crown Prosecution Service at the time of Savile’s crimes, but he was not the reviewing lawyer for the case.
Afterwards he clarified comments saying the Labour leader "had nothing to do personally" with the decision not to prosecute Savile. However, in the following days, one of his longest serving aides, Munira Mirza, resigned her Downing Street role over his refusal to apologise.
Sir Keir has previously described the claim as "a ridiculous slur, peddled by right-wing trolls".
The incident has prompted Conservative politicians to further criticise Mr Johnson for not apologising.
Technology Minister Chris Philip claimed there was "no way you can reasonably make a link" between what the protesters said and the PM's previous remarks.
He said Mr Johnson's comments in the Commons were "capable of being misconstrued", but that he had clarified in the following days that Sir Keir was not personally responsible for the case.
Criticism came from Tory MPs, including Commons defence committee chair Tobias Elwood who tweeted: "Let's stop this drift towards a Trumpian style of politics from becoming the norm."
Labour MP Kim Leadbeater, whose now holds the seat of her sister Jo Cox, who was murdered while serving as a politician, said: "These things don't just happen. Words have consequences, leaders have a duty to behave responsibly and politics is not a game."
Julian Smith, a former Northern Ireland secretary under Mr Johnson, said "the false Savile slurs made against him are withdrawn in full".
And senior Tory MP Sir Roger Gale - who is one of the MPs who has called for Mr Johnson to resign over the Downing Street party row - also said he feared the "grim scenes" outside Parliament were "the direct result of the deliberately careless use of language in the Chamber".
