London: Prime Minister Theresa May on Friday wrote to European Council President Donald Tusk seeking a further extension to the UK's Brexit deadline until June 30 to try and find a solution in Parliament to the current impasse over the terms of Britain's exit from the 28-member bloc.

In her letter, which comes ahead of an EU summit next Wednesday, May told Tusk that while it is "frustrating" that there has been no "orderly" conclusion after her withdrawal agreement was rejected three times by the House of Commons over the controversial Irish backstop clause, the UK remains "strongly committed" to finding a Brexit resolution as soon as possible.
