BORIS Johnson blasted Donald Trump as "completely wrong" for inciting his supporters to storm the Capitol in Washington.
The PM "unreservedly condemned" the scenes of violence on Wednesday which led to the deaths of at least five people.
The violent riots erupted after Trump told supporters to prevent President-Elect Joe Biden's election win being certified: "We're going to walk down to the Capitol.
"And we're gonna cheer on our brave senators and congressmen and women. And we're probably not going to be cheering, so much for some of them, because you'll never take back our country with weakness, you have to show strength and you have to be strong."
Speaking at Downing Street on Thursday, Mr Johnson stormed: "All my life, America has stood for very important things - the idea of freedom, of democracy.
"And as you say, Donald Trump encouraged people to storm the Capitol."
The PM furiously tore into the outgoing President for questioning Mr Biden's election win - accusing him of undermining democracy.
"And in so far as the President consistently has cast doubt on the outcome of a free and fair election, (he) was completely wrong.
"I am unreservedly condemn encouraging people to behave in the disgraceful way that they did in the capitol."
Mr Johnson added that he was "very pleased" Mr Biden had now been formally declared President-elect.
