Brexit, Labour and a former spymaster make headlines on Sunday.

The Sunday Times says the Prime Minister appears set to push back a Commons vote on her Brexit deal after a Cabinet row erupted over a supposed plot to delay Britain’s departure from the EU.

Theresa May has been warned that delaying Brexit would create an inescapable “elephant trap” that would keep the UK in the EU forever, the Sunday Telegraph reports.

The Prime Minister has been urged to hold her nerve against the “enemies” of Brexit by senior Leavers, the Sunday Express reports.

Jeremy Corbyn has been urgently warned to change his approach to Brexit, anti-Semitism and internal conflict by influential party figures, The Observer says.

The founder of Labour grassroots group Momentum has told The Independent that the new Independent Group of MPs is threat to the party.

A former head of GCHQ quit the role after officials discovered he had given a character reference to a serial paedophile, the Mail on Sunday reports.

The Sunday People has carried out an investigation into housing for armed forces families.

And the Sunday Mirror reports that parents are being warned that paedophiles are using a phone app popular with teenagers to target children.
