The UK's Foreign Secretary Liz Truss says she is the "tax-cutting candidate" as she prepares for a summer of campaigning to become Conservative leader and British Prime Minister.
Her opponent Rishi Sunak is promising to take advantage of "the freedoms Brexit gave us" if he is voted in.
The results will be announced on September 5th.
In a video shared on his twitter, Sunak says winning the next general election is a priority.
