European Council President Donald Tusk has congratulated Theresa May on her reappointment as British prime minister and urged her to start talks as soon as possible on Britain's exit from the EU to minimise disruption.
"We don't know when Brexit talks start. We know when they must end", he wrote on Twitter Friday, referring to the 2019 deadline. Do your best to avoid a "no deal" as result of "no negotiations". "I am fully committed to maintaining regular and close contact at our level to facilitate the work of our negotiators". At the same time, European Commission President Jean-Claude Juncker said that a delay in negotiations may be unavoidable, as "The dust in the United Kingdom now has to settle".
The clock is running on how long we can live in a house half built.
The German MEP told BBC Radio 4's Today programme: "One year after the decision by the British people to leave the European Union, we see that Europe, Paris for example, Berlin and even Brussels is very stable, so we are ready, and we see disorientation in London, which is not a positive thing".
"I am not sure that we should read the results of this vote as questioning in any way the position expressed sovereignly by the British on Brexit", said French Prime Minister Édouard Philippe, speaking on French radio.
Guenther Oettinger, the German member of the European Commission, said it was unclear negotiations could be launched on June 19, as planned.
"Brexit negotiations should start when United Kingdom is ready; timetable and European Union positions are clear".
There was clear frustration within the European Union at the failure of the election to deliver a decisive result.
According to an analysis in the BBC, the loss of seats by May's party in the election could make Brexit negotiations more hard, as it raises the possibility that the Prime Minister could be unable to sell the tough trade-offs required by a negotiation at home.
Germany's European Commissioner Gunther Oettinger said "a weaker partner weakens the whole thing", while if both sides were strong "you get results more quickly".
Almost a year after the Britain's watershed referendum, when voters opted to leave the 27-state bloc, the long-awaited Brexit talks are still technically slated to begin June 19.
"We will have to see whether the negotiation chief will remain the same, how the relevant ministers will look".
