Dawn Butler has said that Boris Johnson has taken a leaf out of Donald Trump’s “rulebook” and “it is dangerous”.
Ms Butler, the Labour MP for Brent Central told talkRADIO’s Matthew Wright: “I think Trump has changed the discourse of politics in general.
“I think Trump has come in with this and thrown all the rulebooks in the air whereas before politicians were very mindful and very measured in what they say and in their language.
“I think he kind of said ‘Look!’ and people have looked at it and seen that he has said all of these things that are unsavoury, racist, misogynist and he still got elected.
“I think Boris has taken a leaf out of his rulebook.
“Apparently he has met one of Trump’s special advisors.”
This comes as Mr Johnson’s Daily Mail column received backlash from within the party after comparing Mrs May’s Brexit strategy as a “suicide vest”.
Mr Johnson said: "We have opened ourselves to perpetual political blackmail. We have wrapped a suicide vest around the British constitution - and handed the detonator to Michel Barnier.
"We have given him a jemmy with which Brussels can choose - at any time - to crack apart the union between Great Britain and Northern Ireland."
‘I think it is dangerous’
Ms Butler added: “I think it is dangerous.
“Before we did not have social media underpinning all of that.
“What the Police have said is that we are ignoring the rise of far-right extremists and I think what this narrative does is feed into that.
“We kind of have to be responsible and mindful because you might just think of it as something to get in the papers, get on the front-page but the ripple effects of that runs quite deep.”
Mr Johnson previously caused controversy for comparing women wearing Burkas to "letterboxes" in his Sunday Telegraph column.
