Andy Burnham is expected to announce that he will push ahead with plans for electoral reform in his first conference speech as Labour leader, in the latest sign that he intends to radically transform the UK’s political system.

The prime minister, a longtime advocate of reform, will kick off a process that could eventually lead to ditching the first-past-the-post system in favour of proportional representation.
