Andy Burnham will tell MPs today that failing to secure a closer deal with the European Union would be a "dereliction of duty". The Prime Minister is expected to update Parliament this afternoon after a month-long conference recess.
PM to call for different conversation on Brexit
The Prime Minister, who said last month that Brexit had done more harm than good, will say a better relationship with the bloc could boost economic growth and help tackle illegal immigration.
A No 10 source said: "Andy understands why some politicians don't want to face up to the reality that Brexit has not delivered what they once promised. But it is time for a different conversation about what our long-term relationship should be. Sticking with the status quo and not working relentlessly to secure a good deal that boosts growth would be a major dereliction of duty."
Lib Dems urge dropping red lines
Ahead of the statement, Liberal Democrat leader Sir Ed Davey said Mr Burnham should drop Labour's "red lines" ruling out rejoining the European customs union or single market.
The Prime Minister is also expected to touch on his recent visit to New York for his first meeting with US President Donald Trump and the ongoing Ukraine-Russia war. He is expected to speak around 3.30pm.
Downing Street defends referendum legitimacy
Downing Street said Mr Burnham accepts the result of the Brexit referendum as legitimate despite evidence Russia tried to interfere. The Prime Minister's official spokesman told reporters: "Given everything we know about Russia, it is inconceivable they did not seek to use the referendum to their benefit. But as the minister (Stephen Doughty) said this morning, we do not believe they have succeeded."
The spokesman said the Prime Minister "absolutely accepts the referendum result". After repeated questioning the spokesman added: "Yes, we do believe the referendum result to be legitimate."
