Several audio plays for Big Finish followed, The Holy Terror, The Chimes of Midnight and Jubilee all winning best audio drama in the Doctor Who Magazine polls of their respective years.

Shearman wrote the television episode "Dalek" for the 2005 series of Doctor Who produced by Russell T Davies for the BBC.

Peter Purves is an English television presenter who is best known for being a presenter on the BBC children's programme Blue Peter. After his eleven years on the programme he has continued to make regular appearances since then. In particular, Purves has been associated with television coverage of the Crufts dog show.

Purves was originally an actor, and played the character of Steven Taylor in Doctor Who when The Doctor was played by William Hartnell.

Early life

Purves was born in New Longton, near Preston, Lancashire, and was educated at the independent Arnold School in Blackpool.

He also attended Manchester Polytechnic and is a confirmed atheist.

Doctor Who

Purves first appeared on the show in the role of Morton Dill in "The Chase" after being cast by Director Richard Martin.

At twenty-six years old, Purves first became known to television audiences in 1965 as Steven Taylor, one of the early time-travelling companions in the programme Doctor Who, when the Doctor was played by William Hartnell. Purves has provided DVD commentaries for many of the surviving Doctor Who episodes he appeared in and documents the making of each of his Doctor Who stories in his autobiography, Here's One I Wrote Earlier. Purves was also a good friend of the actor Jon Pertwee, who played the Third Doctor.

Purves has said that he preferred the historical stories on the show.

Blue Peter

After leaving Doctor Who, Purves became a regular presenter on the children's magazine programme Blue Peter from 1967 to 1978. Purves co-presented Blue Peter first with John Noakes and Valerie Singleton and then with Noakes and Lesley Judd, during the programme's so called 'golden age'.

Purves maintained his connection to Doctor Who throughout his time on Blue Peter, often hosting special features on the programme and interviewing the actors. These included many clips from episodes which are otherwise now lost, most notably The Daleks' Master Plan, in which Purves himself had appeared.

Dogs have featured in Purves's career since his Blue Peter days when he was given charge of one of the "Blue Peter Pets", Petra, a German Shepherd cross. He became so closely associated with Blue Peter the programme, "the sensible one", that he found his association difficult to shake off.

Subsequent television appearances

After leaving Blue Peter, Purves presented "Stopwatch" and "We're Going Places" and then later a spell as the front man for darts events on the BBC and as presenter of the long-running BBC1 motorbike trials series Kick Start. He also presented much of the BBC's darts coverage from 1979 to 1983.

His later TV career has included cameo appearances in episodes of the soap opera EastEnders and sitcoms The Office and I'm Alan Partridge. In The Office episode "Training Day" Purves played himself in a customer care training video that David Brent and his staff were being shown (incidentally, Purves is a qualified business trainer and a motivational speaker).

Purves has had a thirty-year association with television coverage of major dog shows such as Crufts and in 2007 his appearance as a judge on the reality TV programme The Underdog Show. Purves also writes for the dog press and regularly presents at dog award shows. Marking his 70th birthday, his 2009 autobiography Here's One I Wrote Earlier was released at The Kennel Club.
