British Prime Minister Boris Johnson has sent an unsigned letter to the European Union requesting a postponement of Brexit, but added another memorandum that he did not want to extend the exit.

Johnson had previously said he would rather "die in a pit" than seek an extension of the exit date after October 31, but a law passed by Johnson's opponents forced him to send a letter to the EU requesting a postponement of the deadline to January 31, after lawmakers thwarted his bid. To approve his agreement to exit the European Union, the day before yesterday.

In an extraordinary step, indicating the depth of the Brexit crisis, Johnson sent three letters in total to the President of the European Council, Donald Tusk. The second was an unsigned photocopy of the text of the law known as Ben's Law, and Johnson said in the third letter that he did not want the extension.

"I have made clear since I took office as Prime Minister, and I have made it clear to Parliament once again my point of view and the government's position that the extension again will harm the interests of Britain, our European Union partners and our relations," Johnson wrote in his third letter. Parliament's exit agreement will be completed before October 31.
