British Prime Minister Theresa Mae on Thursday told the House of Representatives that the BRICEST negotiations had reached a "decisive moment" ahead of a summit of EU leaders on Sunday in Brussels to ratify the divorce agreement and announce the future relationship.

"The negotiations have now reached a decisive moment," she said, stressing "the protection" of Britain's sovereignty over Gibraltar, the British enclave in Spain, which still raises a controversial point in the British-European negotiations.

"The agreement we reached is an agreement between the United Kingdom and the European Commission," the British prime minister told reporters at Downing Street, "Now it is up to the 27 leaders of the other EU countries to study this agreement in the days leading up to the meeting of the Council European special on Sunday. "

"The British people want to resolve this matter, they want a good agreement that sets us a course for a better future, and this agreement is at our disposal and I am determined to conclude it."

She said she had spoken to Spanish Prime Minister Pedro Sanchez. "I am confident that on Sunday we will be able to agree on an agreement that fulfills the full aspirations of the UK family, including Gibraltar," she said.

The BBC's Nina Harbloo said the SNP deputies were not satisfied with the draft agreement, because Britain says it would withdraw from the customs union and the European Single Market. This is rejected by the Scots who voted in favor of staying in the European Union, Because they say that the British prime minister's plan does not serve Scotland's interests and will put the UK Union in danger.

Britain is due to leave the European Union by March 29.
