Author and comedian Adam Kay has announced he is going on his biggest ever tour later this year.

This Is Going to Hurt...More will kick off at Edinburgh Usher Hall on September 7 and come to Cardiff's Motorpoint Arena on Saturday, September 17. 

Kay, 41, from Brighton, has also announced the release of his new book, Undoctored: The Story of a Medic Who Ran Out of Patients in September. 

Stories from the book will be included in the tour, as well as his best-selling book This Is Going to Hurt. 

The book has been made into a new BBC series which has been created, written and produced by Kay. 

The first episode aired on Tuesday, February 8 at 9pm on BBC One and stars Ben Whishaw as Adam. 

The books and series are based on the diaries from Kay's career as a doctor from 2004 to 2010.
