Brexit leads many of Monday’s papers as the debate over Britain’s departure from the European Union continues in Westminster.

The Times reports that Theresa May is “facing the prospect of a leadership battle” as the 48 letters needed to trigger a contest are “likely” to be submitted. Leading the pack, the paper says, is Boris Johnson as the rivals “set out their leadership pitches” over the weekend, the paper says.

The Daily Telegraph leads with Mrs May’s “11th-hour crisis talks” with EU leaders over the “doomed vote” on her Brexit deal. It adds that Mrs May told aides that her vote is “unwinnable”.

The Guardian also runs with Brexit, reporting Mrs May will start a “last-ditch attempt to win over mutinous Tory MPs” with less than 48 hours before the crucial vote.

The Financial Times leads with Crossrail, reporting on delays and cost increases on the new rail project in the south east.

The Metro carries tributes to Grace Millane, a Briton who went missing in New Zealand with a man later charged with her murder.

The Independent returns to Brexit, with a front page riffing on the artwork from a Sex Pistols album.

The Daily Mirror carries a picture of I’m A Celeb winner Harry Redknapp above a story about Mrs May having “24 hours to save her job”.

The Sun leads with allegations against a former chauffeur to the Queen.

And the Daily Mail carries statistics suggesting drug driving is at its highest level since records began with 37 drivers a day failing tests for banned substances.
