Talks over a trade deal with the EU are hanging in the balance amid a stand-off over the UK’s plans to override part of the Brexit withdrawal agreement.
The EU has warned the UK it could face legal action if it does not ditch controversial elements of the Internal Market Bill by the end of the month.
Concerned Conservative MPs have launched a bid to amend the new law.
Boris Johnson hosted a Zoom meeting on Friday with around 250 MPs to discuss the controversial bill.
The prime minister did not take questions and a bad signal meant the video and audio connections were lost for several minutes.
Meanwhile, the European Parliament has announced it will “under no circumstances ratify” any trade deal reached between the UK and EU if the “UK authorities breach or threaten to breach” the withdrawal agreement, which came into force in February, by getting the bill through Parliament.
The dispute is happening with only a few weeks for the UK and EU to agree trade deal before Mr Johnson’s 15 October deadline – after which he says he is prepared to “walk away”.
Informal talks between the two sides are due to resume on Monday amid “significant” differences.
The next official round of talks – the ninth since March – start in Brussels on 28 September.
Mr Johnson’s proposed Internal Market Bill, which will be formally debated in the House of Commons for the first time on Monday, addresses the Northern Ireland Protocol – the part of the Brexit withdrawal agreement designed to prevent a hard border returning to the island of Ireland.
The new law would give UK ministers powers to modify or “disapply” rules relating to the movement of goods between Britain and Northern Ireland that will come into force from 1 January, if the UK and EU are unable to strike a trade deal.
The publication of the bill prompted emergency talks on Thursday, in which the EU said the planned changes must be scrapped or risk jeopardising the UK-EU trade talks.
But the government defied the EU’s demand, insisting it would proceed as planned with the legislation it says is necessary to protect the integrity of the UK and the peace process in Northern Ireland.
When it comes to Brexit, all negotiations are inter-linked: EU-UK trade talks, the process to implement their divorce deal, negotiations on fishing rights and Brussels’ deliberation on UK financial service.
What happens in one area very much affects progress in the others. You cannot separate them entirely.
Which is why this week, as the war of words and wills between Brussels and Downing Street raged over the government’s threat to throw a grenade at key parts of the divorce deal, everyone’s thoughts turned immediately to the trade talks between the two sides.
Could they survive? In fact, they limp on.
Despite bitter arguments over legislation and a huge list of outstanding issues still to be ironed out in bilateral trade talks; despite time and trust running out on both sides; neither the EU nor the UK seem to want to be the first ones to walk out the door.
Business Minister Nadhim Zahawi defended the bill as necessary in case existing “ambiguities” in the withdrawal agreement are not settled through the formal dispute resolution process.
“It’s not about if we implement the withdrawal agreement and the Northern Irish Protocol; it’s how we implement it,” he told BBC Radio 4’s Today programme.
But the prime minister’s approach continues to cause unease within the Conservative Party, with former leaders Theresa May, Lord Howard and Sir John Major among those urging him to think again.
Former Chancellor Lord Lamont said the government was in a “terrible mess” and warned that the Internal Market Bill would not get through the House of Lords in its present form.
Even strong supporters of the government’s overall Brexit strategy and the bill have expressed concerns.
Sir Bernard Jenkin – a member of the pro-Brexit European Research Group (ERG) – told LBC Radio that Mr Johnson “should be more mindful of the reputational damage of playing such hardball”.
Leading Brexiteer and former ERG chairman Steve Baker told Today the UK was “in a bad place” after a “series of very poor decisions”.
He said a solution was “tantalisingly within our grasp” if a free trade agreement could be concluded but the UK should be prepared to “repudiate” the whole withdrawal agreement as the EU had acted in “bad faith”.
Meanwhile, Conservative backbencher Sir Bob Neill, who chairs the Commons Justice Committee, is tabling an amendment to try to force a separate parliamentary vote on the three contentious clauses of the bill.
Gordon Brown has become the latest former prime minister to warn of the damage the move could do to the UK’s international reputation, telling Today it was a “huge act of self-harm”.
