Chris Evans' departure from Top Gear is just the latest twist in the programme's tumultuous history. Here's how it played out.

He was quick to defend himself when detractors labelled him "too shouty and excitable" but just one month on, Top Gear host Chris Evans has decided to walk away from the BBC series.

Posting on Twitter, the radio host announced: "Stepping down from Top Gear. Gave it my best shot but sometimes that's not enough. The team are beyond brilliant, I wish them all the best."

The move marks the latest twist in one of broadcasting's most tumultuous chapters, which began in March last year when Jeremy Clarkson was suspended by the BBC following a "fracas" with his producer.
