A Prison radio station won four prizes at this year's Sony Radio Awards.

Electric Radio, which broadcasts from Brixton Prison, received awards in every category in which it was nominated.

The station won gold in the Community Award and the Listener Participation category, beating off competition from the Adam and Joe show on BBC Radio 6 and Stephen Nolan on Radio 5.

A prisoner's interview with former Belmarsh inmate and Tory ex-minister Jonathan Aitken won bronze for the station in a category where it was nominated alongside Eddie Mair's
grilling of Ken Livingstone on Radio 4. Electric Radio also won bronze in the Speech Award.

Operated by the Prison Radio Association, it is the first in Britain available via satellite, and the first to broadcast around the clock. The judges said: “This is an example of what can be achieved when radio is used for what it does best — an intimate connection to deliver powerful, meaningful content.”

Chris Evans, who hosted last night's ceremony at Grosvenor House in Mayfair, won golds for the Music Radio Personality of the Year — beating fellow nominees Lauren Laverne and Zane Lowe — and the Entertainment Award for his Radio 2 show.

Another Radio 2 DJ, Mark Radcliffe, won Music Broadcaster of the Year.

Radio 3 was named UK Station of the Year ahead of Classic FM and Radio 1. It also won three other music awards.

Radio 5 live landed five Sony golds including the Breakfast award, while LBC's Nick Ferrari won Speech Broadcaster of the Year and Vanessa Feltz on BBC London won Radio Personality of the Year.

The judges said that she “brings humanity and an authentic personality to her programmes”.
