A donor who has given the Conservative party more than £3 million says Prime Minister Boris Johnson should resign as he is past the point of no return.
Financier John Armitage said he thinks leaders should quit if they lose their "moral authority" and criticised the "lack of honour" in politics today.
Mr Armitage's remarks come as Mr Johnson carried out a small ministerial reshuffle and a shake-up of how No 10 operates.
