British Prime Minister Keir Starmer has resigned from his post, the BBC reports.
He officially announced his resignation from Downing Street and said he would remain in office until his successor is appointed.
British political sources say that internal problems and pressure in the ruling Labour Party have led him to this situation. The sources further say that the Prime Minister's decision may have been hastened in the face of intense and continuous political pressure from within the party.
British newspapers report that Starmer may have felt more pressure from within the Labour Party after his main political rival, Andy Burnham, recorded a decisive victory in a by-election for a parliamentary seat in North West England.
After Burnham's controversial victory, Keir Starmer said he was unfit to lead the Labour Party in the next election. His unexpected resignation has sparked intense global attention on who will be Britain's next prime minister.
