My Mad Fat Diary star Sharon Rooney will tonight go head-to-head with Olivia Colman for best actress at a major awards ceremony.

Double Bafta winner Colman is nominated for her roles in hit ITV crime series Broadchurch - which is also up for best drama serial - and gritty Channel 4 drama Run.

Glaswegian actress Rooney is in the running at the Royal Television Society (RTS) awards for her first major TV role on E4 show My Mad Fat Diary.

The show, based on a teenager's diary, is also up for best drama series, up against Peaky Blinders (BBC2) and Utopia (Channel 4).

Rooney, who was touring with a theatre education group when she received an email about trying out for the drama, almost turned down the audition.

She initially refused to read the script thinking it would be to play another "big girl" who is a bully or a victim.
