From the BBC:
Labour has said it is prepared to back another EU referendum to prevent a "damaging Tory Brexit".
Jeremy Corbyn has told Labour MPs the party will move to back another vote if their own proposed Brexit deal is rejected on Wednesday.
Labour's Emily Thornberry said if the parliamentary process ended with a choice of no deal or the PM's deal, the public should decide.
Theresa May is under growing pressure to delay the 29 March Brexit date.
Labour are not yet making clear what their proposed referendum would be on.
When asked to clarify this, a spokesman for the leader's office said: "We've just said we'd back a public vote to prevent a damaging Tory Brexit."
