Britain will have a new prime minister by September after the starting gun was fired on a Tory leadership race this week. 

Nominations will open and close tomorrow with hopefuls whittled down to just two contenders by Thursday.

The winner will be announced on September 5 but with just two party members currently having the necessary support of 20 Tory MPs, the frontrunners are already known.

Former chancellor Rishi Sunak currently boasts a backing of nearly 40 MPs while Trade Minister Penny Mordaunt has 24.
