Trump news - live: Dozens more sexual misconduct allegations against president revealed as he claims Boris Johnson 'will do a lot' for US

Donald Trump has been accused of 26 further counts of sexual misconduct in a forthcoming new book, All the President's Women by Barry Levine and Monique El-Faizy, which recounts him hiding behind a tapestry in order to allegedly molest a woman at his resort at Mar-a-Lago in Florida in one instance.

The president's refusal to co-operate with the impeachment inquiry into his dealings with Ukraine - which he accidentally branded a “Wirch Hunt” on Twitter – has prompted House speaker Nancy Pelosi to hit back, reminding the president: “You are not above the law. You will be held accountable.”

The White House issued an eight-page letter to House Democrats late on Tuesday denouncing its investigation into whistleblower allegations that Mr Trump attempted to extort dirt on a domestic political rival from a foreign power as “constitutionally invalid”, after blocking US ambassador to the EU Gordon Sondland from appearing on Capitol Hill earlier in the day to give his version of events.
