United Kingdom Prime Minister Theresa May has said UK’s transition out of the EU could be extended by “a matter of months” to ensure no hard border in Northern Ireland.
The prime minister said this was a new idea that had emerged in negotiations and was not expected to be used.
The UK leaves the EU in March, and the current plan is for a transition period to finish at the end of 2020.
Some Tory MPs and Brexit campaigners are angry at the idea of the UK being tied to EU rules for longer.
It comes after a summit of EU leaders in Brussels failed to make decisive progress in reaching an agreement.
Mrs May addressed her 27 European counterparts on Wednesday evening, urging them to give ground and end the current Brexit deadlock.
Speaking on Thursday morning, Mrs May said that the UK had already put forward a proposal to avoid the need for either a hard border or a customs border between Northern Ireland and the rest of the UK.
She added: “A further idea that has emerged – and it is an idea at this stage – is to create an option to extend the implementation period for a matter of months – and it would only be for a matter of months.
“But the point is that this is not expected to be used, because we are working to ensure that we have that future relationship in place by the end of December 2020.”
The UK is due to leave the EU on 29 March 2019, and the transition period, which Mrs May prefers to call the implementation period, is designed to smooth the path to a future permanent relationship.
During this period, which is due to finish on 31 December 2020, the UK’s relationship with the EU will stay largely the same.
