Early career

After training at Webber Douglas Academy of Dramatic Art, Kemp received his Equity card when appearing alongside John Thaw and Richard Wilson at the Palace Theatre, Westcliff-on-Sea.

Kemp went on to feature in training films for the Ministry of Defence and the ITV soap opera Emmerdale Farm (now Emmerdale) as Graham Lodsworth. Guest appearances in London's Burning and Birds of a Feather followed, before he had a minor role in the 1987 film Playing Away alongside Neil Morrissey.^[3]

In 1990, Kemp appeared in an edition of the Anglia Television police drama The Chief. The episode, entitled Call Sign Bravo, saw Kemp play the role of Police Constable Dennis Scovell. Around the same time he also starred in a golf themed advert for Kellogg's Fruit & Fibre cereal.^[4]

EastEnders

Kemp's best-known role is that of hardman Grant Mitchell in the BBC soap opera EastEnders. Making his debut in February 1990, his character quickly became part of the soap’s key storylines during the 1990s, particularly troubled marriages to Sharon Watts (Letitia Dean) and then Tiffany Mitchell (Martine McCutcheon), as well as the "Sharongate" storyline, which saw brother Phil Mitchell (Steve McFadden) having an affair with Grant's wife, which was uncovered two years after it began.

Kemp announced on 24 March 1999 that he would be leaving the soap later that year after nearly 10 years. His exit was aired in October 1999 when his character moved to Brazil after surviving a car crash. Kemp refused to rule out an eventual return to EastEnders, and various media reports over the next few years speculated that he would return to the series at some stage. In early 2005, the BBC confirmed that Kemp would be returning to EastEnders in the autumn of that year after six years away. It was co-star Barbara Windsor who convinced him to return, even though his comeback would only be a relatively brief one.^[5] His first comeback lasted just a few weeks from October 2005, but he returned again in March 2006, before departing once again in June that year.

In January 2016, it was confirmed that Kemp would make a brief return to the show for the death of Grant's on-screen mother, Peggy Mitchell (played by Windsor), appearing in three episodes during May of that year.^[6] He later filmed a further three weeks and returned again for brief stints from 4 July to 9 September 2016.

Other roles

Following his initial departure from EastEnders, Kemp moved from the BBC to ITV for a reported £1.2 million two-year deal.^[7] Kemp's first role for ITV was in Hero of the Hour. During its filming, on 27 October 1999, Kemp required hospital treatment after being shot in the face when a stunt went wrong. He suffered cuts to his chest and face after safety glass shattered, and was also hit in the face by the discharge from a blank round. He was treated at the scene by paramedics and made a full recovery.

In 2000, Kemp starred in ITV's A Christmas Carol. He took the lead roles in the television series Without Motive and In Defence in 2000, and in 2002's Ultimate Force, where he played Army Staff sergeant Henry Garvie from the British Special Air Service. He continued to appear in this role until 2006. He also played "Cirra" in the 2004 TV film, Spartacus.

In 2005, Kemp appeared in an episode of BBC's Extras and in a two-part adaptation of the Gerald Seymour novel A Line in the Sand for ITV. He has also presented on The Friday Night Project and appeared as a stand in host on The Paul O'Grady Show (2007, 2008).

Kemp appeared in the 4th episode of Series 14 of BBC's motoring show Top Gear. He was the "Man in Boot" of a Renault Twingo Sport being tested by Jeremy Clarkson. The test ended with Clarkson driving the car off the quayside of Belfast Harbour, after which Clarkson joked that Kemp had been killed.^[8] Kemp also appeared in Series 1, where he did a 1 minute 54 seconds (wet) in the "Star in a Reasonably Priced Car" segment.

In 2022, Kemp began presenting the game show Bridge of Lies, airing on weekdays on BBC One,^[9][10] as well as a series of celebrity specials broadcast on Saturday evenings.^[11] Kemp told The Sunday Post: "I am the last person that should be hosting a game show, but it seems to work [...] the landscape of TV has changed significantly in the last six, seven years. Actors once upon a time didn’t do commercials, now A-listers do them. If you worked in television, you couldn’t be in movies or if you were in movies you’d never touch TV [...] that snobbery I would suggest is dissolving. And that’s got to be a good thing I guess."^[12]
