Career: Kemp has rarely been out of work since graduating in 1985. His first credited TV appearance was in Emmerdale in 1986. He also appeared in a string of Kellogg's adverts and featured in such series as Birds of a Feather and London's Burning, before landing the role of Grant in EastEnders - the part that made him a household name. He left in 1999 after nine years. He then appeared in A Christmas Carol, Ultimate Force, In Defence, Hero of the Hour, A Line in the Sand, and a TV remake of Spartacus. In 2005, he featured in an episode of Extras and made a brief, but much-publicised return to EastEnders. He has also hosted a number of hard-hitting documentaries for Sky1, including the Bafta-winning Ross Kemp on Gangs.

Career: In the late 1990s, Baker toured around the north of England with a 1970s comedy disco-dancing revival show called Disco Inferno. He did freestyle routines with back flips and juggled wooden clubs. After finding out that Blue Peter were looking for a new presenter, he sent the BBC a showreel and managed to secure an interview. During his seven years as a Blue Peter presenter, he won two Baftas for Best Children's Presenter. He left the show in 2006 and went on to co-present Countryfile Summer Diaries, Open Country, Animal Squad, Countryfile, Secret Britain and One Man and His Dog. After a stint as a guest presenter on The One Show, he became a permanent host alongside Alex Jones in early 2011. He participated in Strictly Come Dancing in 2010, partnering professional dancer Aliona Vilani, and finished runner-up.
