LONDON: British Prime Minister Boris Johnson said U.S. President Donald Trump was "completely wrong" to encourage his supporters to storm the Capitol on Wednesday.

"And as you say, as you suggest, in so far as he encouraged people to storm the Capitol and in so far as the president consistently has cast doubt on the outcome of a free and fair election, I believe that that was completely wrong," he told a news conference on Thursday.

"And I unreservedly condemn encouraging people to behave in the disgraceful way that they did in the Capitol."
