Over in the UK, Liz Truss has resigned from her role as Prime Minister, and there's been plenty of speculation about who will replace her.

Boris Johnson has been spotted flying back to the UK from a Caribbean holiday, but there's no official confirmation as to whether or not he'll run for Prime Minister again.

Rushi Sunak is another candidate who may be a front runner, but he hasn't made any official statements confirming that he'll run either.

The deadline for candidates to officially confirm that they'll be running is Monday October 24th, 2pm (UK time). In the lead up to the big day, UK correspondent Gavin Grey, joined us to talk us through the possible options.
