LONDON, Oct. 19 (Xinhua) -- UK Prime Minister Boris Johnson has sent a letter to the European Union (EU) to request a Brexit delay, but he refused to sign it, according to British local media BBC and Sky news.

The request would be accompanied by another letter, signed by Johnson, which says he does not want a delay, reports said.

British lawmakers on Saturday voted for a key amendment to force Prime Minister Johnson to seek another Brexit extension from the EU.
