The Tory MP Sir Bob Neill has called on Boris Johnson to quit, dealing another blow to the prime minister’s hopes of drawing a line under the Partygate scandal.

The MP for Bromley and Chislehurst in south London said he had submitted a letter of no confidence because the string of rule-breaking parties across Westminster had “undermined trust in not just the office of the prime minister, but in the political process itself”.
