A prime minister, a plotter and others say farewell as British MPs

In a not terribly strong field, Michael Gove has been the Conservative Party’s most effective minister of the past decade and a half. He pushed through colossal education reforms, which removed schools from local-authority control. England’s relative improvement in international maths and reading tests suggests they have worked. During a two-year stint in the agriculture ministry, Mr Gove laid plans for farmers to be paid not for cultivating land, as they had been for decades, but for delivering public goods like trees and bird-nesting sites. Despite loud grumbling from growers, his successors have stuck to it.
