PM must commit to low taxes or risk losing next election, says David Frost

Former Brexit minister also calls for shake-up of Boris Johnson's advisory team in first major interview since resigning from cabinet

Boris Johnson's former Brexit minister who quit last month has warned him to commit to low taxes and the free market or risk losing the next election, as the prime minister comes under continuing pressure from the Conservative right.

David Frost, a former lobbyist whom Johnson made his chief Brexit negotiator and later gave a peerage, said in his first major interview since quitting as a cabinet minister that the Tories needed to focus on rebuilding the nation and be proud of our history".
