British Prime Minister Theresa May will request a short delay to Brexit in a letter to the European Union on Wednesday, the BBC and Sky reported.

The delay, nearly three years since the United Kingdom voted to leave the European Union, leaves the Brexit divorce uncertain with options including leaving with May's deal, a longer delay, a disruptive exit, or even another referendum.

Just 9 days before the March 29 exit date, May is due to write to European Council President Donald Tusk to ask for a delay.

But the ultimate length of the delay was unclear amid the political chaos in London, with the BBC reporting that May would not ask for a long delay.
