LONDON (AA): British Prime Minister Boris Johnson and European Commission President Ursula von der Leyen have agreed to continue negotiations on a post-Brexit trade deal until Sunday, according to a statement from Downing Street. Johnson said there were still “significant obstacles” which remain after his discussion on post-Brexit trade deal with Von der Leyen in Brussels. UK and EU will continue with negotiations till Sunday when a firm decision should be taken about future talks.

“We had a lively & interesting discussion on the state of play on outstanding issues,” Von der Leyen said in a statement posted on her Twitter account.

“We understand each other’s positions. They remain far apart,” she noted.

“The teams should immediately reconvene to try to resolve these issues. We will come to a decision by the end of the weekend.”

The statements follow a dinner meeting between the two leaders in Brussels on Wednesday evening, which was seen as a last-ditch effort to secure a deal.

“A frank discussion” was held about the “significant obstacles” that remain in the negotiations, according to local media reports quoting a senior source from Downing Street.

“It is still unclear whether these can be bridged,” said the source.

Johnson and Von der Leyen have agreed to further discussions over the coming days between their negotiating teams, and the prime minister “does not want to leave any route to a possible deal untested.”

Johnson said Wednesday before his departure to Brussels that some of the conditions on a post-Brexit trade deal are “unacceptable.”

Britain said Tuesday that it will drop articles of its Internal Market Bill which contradict the UK Withdrawal Agreement.

Cabinet Office Minister Michael Gove said an “agreement in principle” on all issues in the UK-EU Withdrawal Agreement Joint Committee was reached following a meeting with European Commission Vice President Maros Sefcovic.

The trade deal needs to be finalized and ratified should it be agreed upon before the transition period ends to avoid chaos for businesses.

The UK left the EU at the end of January, but a transition period to allow the parties to work on a trade deal kicked in until the end of the year.
