Labour’s deputy leader said: “We believe Boris Johnson cannot stay in Downing Street for a single minute. He has proven to be unfit to govern and so the Conservative Party needs to elect someone to lead their party very quickly or get an interim leader because he is not someone who has been disgraced, who has lost the confidence of his party, how rather the British public. “If they don’t, we are very clear that we will table a motion of no confidence before the summer holidays [July 21] to ensure that this exchange happens and that the Conservative Party does the right thing by the British public, which it has not done, frankly, in recent months.” Pressed on when the vote could take place, Ms Rayner told Sky News: “We will speak to the whips and do it as soon as possible if it is [necessary]. We don’t have much time for a break, honestly. “It could be as early as next week, yes, because we don’t have long before the summer holidays.”
