Keir Starmer's allies are battling to block an 'unhelpful' Labour conference debate on unwinding Brexit.
A motion proposed by the Labour Movement for Europe calls for the party to negotiate closer ties with the EU including a new visas deal.
The text - said to be backed by shadow chancellor Rachel Reeves' constituency group among others - stresses that campaigning to rejoin the bloc immediately would not be in the country's 'best interests'.
But it says the government's 'hard Brexit' agreements should be watered down to 'salvage' as much 'trade and opportunity' as possible.
