Boris Johnson yesterday fired the starting gun on a Conservative leadership race which should make the winner Prime Minister. Meg Russell, Alan Renwick and Robert Hazell pose five key questions which Conservative MPs and others are encouraged to ask the party leadership candidates, based on recent public, parliamentary and expert concerns.

Boris Johnson’s premiership has been marked by ever-growing concerns about the maintenance of various constitutional standards, which in recent days have reached fever pitch. These were echoed repeatedly in ministerial resignation statements and calls for him to go. Recent opinion polls meanwhile show strong public support for constitutional standards of integrity and accountability.

Conservative MPs now have an opportunity to choose among candidates to take Johnson’s place, which also creates an important constitutional responsibility. A high priority when picking the next Conservative leader should be to restore the standards essential to UK democracy, in order both to rebuild integrity in politics, and to work towards rebuilding public trust.

This blogpost sets out five key questions for Conservative leadership candidates, reflecting concerns raised by the public, independent expert organisations, and MPs themselves. Conservative MPs and others are encouraged to prioritise these questions, and raise them with the candidates when the party is making its choice.
