Theresa May is looking to reverse her initial plan to stop European Union citizens arriving in the United Kingdom during the Brexit transition phase, it has been reported.
May is reportedly gearing up to bow to the pressure put on her by Brussels by giving permanent residency to European Union migrants who arrive in the United Kingdom during the Brexit transition period.
"It's one way of getting frictionless trade but it's not the only way", he told BBC radio.
Theresa May is facing the threat of a Commons rebellion on staying in the customs union after a marathon gathering of senior Cabinet members met to find a united front on EU withdrawal. A customs union was the "practical, real world answer" that solved some of the toughest questions, including over the future of the Irish border, and challenges faced by business, Carolyn Fairbairn, head of the Confederation of British Industry, said in January.
A faction of the Labour Party led by Chuka Umunna MP has been pushing to persuade their leader, Jeremy Corbyn, to back a second referendum as well as keeping Britain inside the EU's Single Market and Customs Union, tied to many of its rules and regulations.
Remainer rebel Anna Soubry revealed on Twitter she had cross-party support for a new amendment to the Government's trade bill which would mandate the United Kingdom to form a customs union with Brussels after Brexit.
The address is expected to take place somewhere in Britain, after recent big Brexit speeches in Munich, Germany, and Florence in Italy.
The customs union is at the heart of contention over the UK's position, with those who backed Remain wishing the country to remain within the existing union, or at least a newly constructed union that has some of the benefits.
However, the plan - which appears to have been thrashed out at the Cabinet meeting - is likely to face a muted response in Brussels, which has repeatedly stressed that Britain would not be able to "cherry pick' the deal it struck with Europe".
In recent days, a number of hard-line pro-Brexit MPs have suggested in the British media that the historic 1998 Good Friday agreement should be cancelled due to the difficulties it is causing a hard Brexit.
Staunch Brexiteers oppose continued customs union participation because it would prohibit Britain from signing its own free trade deals after it has left the bloc.
