The European Commission’s trade directorate general and the U.S. Trade Representative are assessing the impact of Britain’s anticipated exit from the European Union on the Transatlantic Trade & Investment Partnership under negotiation between the EU and U.S.

“All these questions will be looked into,” EC trade spokesman Daniel Rosario says as the U.S. and EU prepare for a 14th round of TTIP talks to be held in July in Brussels.

Other EU officials have said they want to agree on consolidated texts highlighting the final sticking points regarding regulatory cooperation at that meeting. The goal is to give negotiators a chance to strike a final deal before President Obama leaves office in January, but it is not known whether Thursday’s U.K. referendum in favor of leaving the European economic bloc will slow that progress.

Obama already has said Britain would be at the back of the queue for a trade deal with America, perhaps long after TTIP is concluded with the rest of the EU.

An agreement by the EU to prioritize free-trade talks with the U.S. and other countries, made within the European Council’s February offer of special treatment for the U.K. – a deal secured by Prime Minister David Cameron, who resigned after Friday’s so-called Brexit vote – no longer stands.

That agreement said EU heads of government accepted the “importance of…the need to conclude ambitious bilateral trade and investment agreements with third countries, in a spirit of reciprocity and mutual benefit.

“Work must be advanced in negotiations with the U.S., Japan and key partners in Latin America, notably Mercosur (the 5-nation South American trade bloc) and in the Asia-Pacific region.”

A joint statement released Saturday by senior EU officials, including EC President Jean-Claude Juncker, says this deal “will now not take effect and ceases to exist.”
