Boris Johnson: EU gives fresh Brexit ultimatum as Supreme Court told 'mother of parliaments shut down by father of lies'

Good morning and welcome to The Independent's live coverage of events at Westminster and beyond.

Boris Johnson has been warned to “keep his nose out” of the Supreme Court case after he filed a written submission telling senior judges they have “no jurisdiction” over his suspension of parliament.

Ahead of the second day in the landmark hearing, Johnson said it would be “constitutionally inappropriate” for the judiciary to intervene in the prorogation – and warned the judges they risk “entering the political arena”.

Labour frontbencher Angela Rayner said: “The PM should keep his nose out of proceedings and let the Judges make their considered decision, they don’t need interference and warnings or finger wagging from anyone, especially from the bungling PM.”

Boris Johnson’s “humiliation” at the hands of Luxembourg over podium-gate will make a Brexit deal harder to reach, some EU officials believe.

In a slightly farcical development, the UK government claims it has put forward proposals to end the Brexit deadlock – but will not allow EU negotiators to keep hold of the written details for fear of leaks.

Brussels is becoming increasingly frustrated that no “concrete” suggestions to replace the Irish backstop have been submitted.

But British sources insisted papers setting out Boris Johnson’s position had been shown to the EU side, even though they were taken back at the end of meetings.

“We are showing them papers,” a government source claimed. “The difference is we are not leaving them with them.”

“Once you share it with 27 countries you are not in control of the document.”

The UK side has produced a version of the Withdrawal Agreement with the backstop removed to show Brussels officials what changes Mr Johnson requires. It has also shown the EU side some of the proposals to replace the backstop.

Labour would put a “sensible” Brexit deal to the public in a new referendum and abide by the result of the vote, Jeremy Corbyn has pledged – suggesting he will resist calls from party activists to explicitly back Remain.

Poland’s ambassador to the UK, who has written a letter to 800,000 Poles advising them to “seriously consider” returning to their home country, has said he is concerned about the settled-status application process.

Speaking on BBC Radio 4’s Today programme, Arkady Rzegocki said of the procedure: “It is straightforward but we are concerned about this process a little.

“Many people do not realise they have to register as they have lived here for many years ... even if they have resident status, they still have to register.”

Rzegocki added: “There are quite a lot of problems with people trying to receive settled status. People who have been here five or 10 years have also had problems.”

Analysts at the Cicero Group think Boris Johnson could get a revised Brexit deal passed in the Commons.

Labour’s ruling body has backed a call to replace the party's student organisation with a new one.

The party’s National Executive Committee (NEC) supported a motion calling for Labour Students to be effectively abolished.

A Labour Party source said: “The NEC has asked staff to draw up proposals for a reformed student organisation that complies with the rules and represents the tens of thousands of students in our party.”

The NEC motion was put forward by the founder of the Jeremy Corbyn supporting Momentum group, Jon Lansman, and was approved just days before the start of the annual Labour Party conference.

Jess Phillips, the Labour MP for Birmingham Yardley, is among criticising the move.

European Commission president Jean-Claude Juncker has said progress on replacing the backstop could not be made to reach a deal until the UK submitted written proposals.

Speaking at the European Parliament following his meeting with Boris Johnson earlier this week, he said “the risk of a no-deal remains real” but that would be the choice of the UK government.

“I said to prime minister Johnson that I have no emotional attachment to the safety net, to the backstop, but I stated that I stand by the objectives that it is designed to achieve,” he said.

“That is why I called on the prime minister to come forward with operational proposals, in writing, for practical steps which would allow us to achieve those objectives.

“Until such time as those proposals have been presented I will not be able to tell you, looking you straight in the eye, that any real progress has been achieved.”

Juncker also told MEPs that his talks with Johnson had been “friendly, constructive and in part positive”.

“The Commission is prepared to work day in day out, morning until night - with a few breaks - to try to find the technical and political solutions we need but I am not sure that we will get there,” he said.

“There is very little time remaining but what I do know is that we have to keep trying.”

The EU’s chief negotiator Michel Barnier said that they still needed to hear more from the UK side about its proposals for replacing the Northern Ireland backstop.

“The position of the European Union has never been an ideological one. It has always been a pragmatic one,” he said.

“The new UK government this week in Luxembourg outlined the aspects of the backstop they don’t like. That is not enough, however, to move towards achieving a solution,” he said.

“We need a legally operative solution in the Withdrawal Agreement which addresses each one of the risks created by Brexit.”

Barnier acknowledged the concerns expressed by Johnson about the backstop.

“We understand the remarks of the UK prime minister on the democratic or non-democratic nature of the backstop,” he told MEPs.

“But it is up to the UK government to ensure the support of the Northern Ireland institutions to the Withdrawal Agreement because it would be signed on behalf of all of the UK.”

“I think we need to move forward with determination, we need to do so with ongoing co-operation and transparency.”
