The EU's executive Commission said in a statement Friday that the first round of negotiations in Brussels will be part of a "sequenced approach to the talks".
Brexit Secretary David Davis will call for a "deal like no other in history" as he heads to Brussels to launch negotiations for Britain's exit from the European Union. "We want to see a Brexit that works for everybody, not just in Northern Ireland from my perspective but in the Republic of Ireland as well, so it is about a sensible Brexit", Foster told reporters.
Britain has less than two years to negotiate the terms of the divorce and the outlines of the future relationship before it is due to leave in late March 2019.
British Foreign Secretary Boris Johnson said Monday he still thinks that the Brexit negotiations will yield "a happy resolution that can be done with profit and honor for both sides". However, the Tories faced strong criticism and opposition from other parties.
The election debacle has left her weakened and fuelled speculation over her position.
"These talks will be hard at points, but we will be approaching them in a constructive way".
"What can you say of meaning about such chaos?" the diplomat asked.
"The question is not whether we're leaving the Customs Union, the question is what do we put in its place in order to deliver the objectives, which the Prime Minister set out in the Lancaster House speech, of having no hard land border in Ireland, and enabling British goods to flow freely backwards and forwards across the border with the European Union".
The scenario has been initially proposed and promoted by the ruling Conservative party.
Amid such upheaval, though, there is little agreement on what kind of Brexit May should try for - even assuming she can hold onto her job.
British Prime Minister Theresa May has said that the vote one year ago was partly a vote for Britain to control its borders, and has said that Britain will leave Europe's single market, as membership is incompatible with restricting immigration. However, it seems unlikely he will be able to resist public comment on the Brexit process, which he has described as a "tragedy".
"But what we are trying to get is tariff free access to the single market".
In Luxembourg, Britain's finance minister said that protecting jobs and the economy should be the main focus in upcoming discussions.
The first issue at the Brussels talks will be the status of millions of European Union citizens living in the United Kingdom and British residents of the other 27 countries, including their right to stay, to work, and to access medical care.
Britain's financial obligations are expected to amount to at least $64 billion, and could go over $100 million, although London has suggested it will not pay that much.
Britain's ambassador to the European Union will be expected to gather information on the 27's thinking and feed it back to Mrs May, including on where there could be chinks in the armour for the United Kingdom to exploit. "SENSIBLE BREXIT" May wants to negotiate the divorce and the future trading relationship with the European Union before Britain leaves in March 2019, followed by what she calls a phased implementation process to give business time to prepare for the impact of the divorce.
The EU has insisted that this sequence involve sorting out Britain's departure and urgent issues like the rights of citizens affected by Brexit before the shape of future ties or trade are discussed.
