The book, which so far has only a working title ‘Nick Clegg: The Biography’, is being written by the writer and broadcaster Chris Bowers, and will be published by Biteback in time for next year’s party conference season.

“We’ve been looking to appoint a biographer of this year’s breakthrough figure in British politics,” says Biteback’s managing director Iain Dale, “and in Chris Bowers we believe we’ve found an experienced biography writer in the perfect position to give the background on who Nick Clegg is and what drives him.”

The book will chart Clegg’s rise from MEP to deputy Prime Minister and lynchpin in the historic coalition government. It will also look at the extraordinary family history that helps define him as a politician.

Bowers, 49, is a journalist and commentator, and author of the recent best-selling biography of the tennis ace Roger Federer.

He also works as a communications consultant for the European Federation for Transport & Environment and is a Lib Dem district councillor in East Sussex, he worked loosely with Clegg on revising the Lib Dems’ environment policy in the run-up to the last Lib Dem leadership election.
