Explainer: What is the latest disruption to hit the Brexit trade negotiations?

The European Unionâs Chief Brexit Negotiator Michel Barnier arrives at 10 Downing Street (PA)
The Brexit process has been thrown into fresh turmoil by reports of UK Government moves to bring in new laws which would override parts of the Withdrawal Agreement from the EU.
â What are ministers proposing?
The reported move would get rid of the requirement for new customs arrangements in Northern Ireland.
It has been reported that the Internal Market Bill would end the legal legitimacy of the Withdrawal Agreement in areas such as NI customs and state aid and financial assistance.
At present Northern Ireland is supposed to adhere to some EU regulations after the Brexit transition period ends on December 31 in a bid to stop a âhard borderâ on the island of Ireland.
The British Government has indicated it is a necessary move in case trade talks fail.
The UK has formally left the EU, but adheres to the blocâs trade rules and regulations until the end of the year.
A trade agreement was intended to be worked out by then, but the process has been slow and acrimonious, particularly regarding issues such as fishing rights.
Both sides have said a deal would need to be done by mid-October in order for it to be ratified in time.
Not well. Irish Foreign Minister Simon Coveney has branded the UK course of action âunwiseâ.
And EU chief negotiator Michel Barnier said he will be seeking clarification of the UKâs plans.
It is playing it down.Â
UK Environment Secretary George Eustice insisted the measures are intended to tie up âloose endsâ and not meant to rip up the agreement with the EU.
He told the BBC: âWhat we are talking about here is what type of administrative customs processes you might have for goods that might be at risk of entering the EU single market â going from GB to Northern Ireland. These are important but minor technical details.â
Labour has accused Prime Minister Boris Johnson of misleading people.
UK Shadow health secretary Jonathan Ashworth told the BBC: âBoris Johnson, I thought, told us he had an oven-ready deal. And, he fought a general election telling us he had an oven-ready deal; now suggests that he was misleading people in that general election.â
The eight rounds of talks between Britain and the EU begins on Tuesday, and the British Government is expected to outline its proposed new legislation on Wednesday.
