It is often said that political power in the UK is increasingly concentrated in the hands of the Prime Minister and a cadre of unelected advisers, prompting many commentators to announce the demise of Cabinet government.

It will examine the peculiarities of coalition politics, continuities and ruptures with previous government practice and, finally, ask whether or not the return of Cabinet government is realistic or even desirable.
