Labour has accused Theresa May of "running scared" of Parliament after Brexit secretary, Dominic Raab, was the one to update MPs on the state of the negotiations.
It comes after Arlene Foster, the leader of the Democratic Unionist Party, which is responsible for propping up the prime minister's fragile government, travelled to Brussels for talks with the EU's chief negotiator, Michel Barnier.
"It's outrageous the PM isn't making the statement. She was the one negotiating in Salzburg, so she should be the one explaining to MPs why she failed," a Labour source told The Independent. "At this stage the PM shouldn't be running scared of Parliament".

DUP Westminster leader Nigel Dodds declared it was “rubbish” to say a backstop was needed to avoid a hard border in Northern Ireland. He repeated his stance that the DUP will not tolerate anything that separates Northern Ireland from the rest of the UK.
Mr Raab said the government will honour all the commitments it made in December and pledged not to do anything that would threaten the integrity of the UK.
Mr Raab replied that the UK could impose new border checks because it would no longer be bound by EU rules.
He added: "On the withdrawal agreement, while there remains some differences, we are closing in on workable solutions to all of the key outstanding issues, building on the progress we made during the summer on issues such as data and information, the treatment of ongoing police and judicial co-operation in criminal matters and ongoing union judicial administrative procedures after the date of exit.
"We have also been discussing our proposals on the linkage needed between the withdrawal agreement and the future relationship, and the EU is engaging constructively."
