MPS are too late to prevent a no-deal Brexit, Boris Johnson’s most senior aide has said. Dominic Cummings told ministers and officials that the Prime Minister will honour his October 31 pledge even if Jeremy Corbyn and pro-Remain ­Conservatives succeed in forcing a general election.

In a series of explosive briefings last week, Mr Cummings suggested that the Labour leader had missed his ­opportunity to secure an election ­before the UK’s intended departure date from the EU.

If Mr Johnson loses a no-confidence vote when the Commons returns in September, potentially leading to a general election, the Prime Minister would have the power to schedule the poll for after Hallowe’en, Mr ­Cummings disclosed.

He also claimed that an election would lead to a Conservative majority.

The Telegraph has pieced ­together Mr Johnson’s Brexit strategy based on numerous accounts of Mr Cummings’s briefings and interventions, as he set out to government staff and ministers how Mr Johnson would deliver Brexit on Oct 31 even if the EU refuses to drop the Irish border backstop agreed by Theresa May.
