Rishi Sunak and Liz Truss are doing battle to become the next Prime Minister in a six-week contest to secure the support of Tory members.
Conservative MPs whittled the eight-strong field of hopefuls down to the final two, with the winner to be decided by the party membership in September.
The candidates have shifted their attention away from Westminster to the 160,000-strong membership over what promises to be a long and fractious summer of campaigning.
Ballots start arriving for Conservative members this week and they have until September 2 to decide whether to elect millionaire Sunak or Iron Lady wannabe Truss to be the next PM.
Members were originally due to get two ballots - a physical ballot paper through the post, and a pair of unique security codes that allows them to vote online.
This would have allowed them to change their minds during the contest - with the most recent ballot accepted.
But party chiefs tore up these rules due to hacking fears, which also delayed the arrival of ballots.
The candidates are travelling across the country to make their case to the party's grassroots, taking part in 12 hustings where they will be grilled by members.
These members-only events, which will be streamed online, started on July 28 in Leeds and run until August 31 in London.
Both candidates will also take part in a Sky News clash on Thursday, August 4.
The new Prime Minister will be named on September 5.
Here are the remaining hustings dates in full:
5th August: Eastbourne
9th August: Darlington
11th August: Cheltenham
16th August: Perth
17th August: Northern Ireland
19th August: Manchester
