The Apprentice UK (season 5)

The fifth series of British reality television series The Apprentice UK was broadcast in the UK on BBC One, from 25 March to 7 June 2009. Because of ITV's live coverage of a 2010 FIFA World Cup qualification match involving England, the final episode was broadcast three days earlier to avoid clashing with this. It is the last series to feature Margaret Mountford as one of Alan Sugar's aides, after deciding to leave following the conclusion of the fifth series to focus on her education, although she would retain a place in the programme until the end of the ninth series. Alongside the standard twelve episodes, two specials were aired alongside this series – "The Final Five" on 3 June; and "Why I Fired Them" on 5 June.

The winner of this season was TBA.

This series was preceded by series four and followed by series six.
