LONDON/BRUSSELS—British Prime Minister Theresa May wrote to European Council President Donald Tusk on Friday asking for a delay of Brexit until up to June 30, but said she aims to get Britain out of the EU earlier to avoid it participating in European elections.
An EU official signaled that Donald Tusk, the chairman of EU leaders, could be willing to offer even longer: up to a year for Britain’s feuding politicians to agree and ratify a plan.
