Disgraced veteran broadcaster Stuart Hall had his 15-month prison sentence for sex offences doubled by judges at Britain's Court of Appeal.

Lord Chief Justice Lord Judge, Lady Justice Rafferty and Mrs Justice Macur, sitting in London, ruled that the original 15 months was "inadequate" and should be upped to 30 months.

Hall, 83, from Wilmslow, Cheshire, had admitted 14 counts of indecent assault against girls as young as nine between 1967 and 1987.

He kept his head bowed as he listened to proceedings via video link from HMP Preston and showed no reaction as the decision was announced.

The case was referred to the court by Britain's attorney general Dominic Grieve, who argued that Hall's sentence was "unduly lenient", as it failed to adequately reflect the gravity of his offending and the "public concern" about such crimes.

The Former It's A Knockout presenter was sentenced to the 15 months at Preston Crown Court last month.
