"Honestly, I leave London with a feeling that the Government is undecided about how and when they should trigger Article 50, also with the feeling that they perceive, more and more, the European side — the 27 institutions in Brussels and Strasbourg — can't wait too long," Schulz said, as quoted by The Independent newspaper, in his speech at the London School of Economics.
On Thursday, Schulz met with UK Prime Minister Theresa May to discuss the United Kingdom's departure from the European Union.
Earlier on Friday, UK’s Foreign Secretary Boris Johnson said that the process of leaving the European Union for the United Kingdom would begin after invoking Article 50 of the EU Lisbon Treaty at the beginning of 2017, adding that it could be completed in less than two years.
Article 50 states that any country that wishes to leave the European Union must formally inform the European Council about its decision and then will have a period of two years to negotiate the terms of its withdrawal.
On June 23, the United Kingdom held a referendum in which 51.9 percent of voters, or 17.4 million people, opted for the country to leave the European Union.
