Former Lostprophets singer Ian Watkins will contest his 35-year sentence for a string of child sex offences today.
A panel of judges at Cardiff Crown Court will decide whether the convicted paedophile has grounds for appeal.
The 37 year old, who is not challenging his 13 sex offence convictions, believes he was treated too harshly by sentencing judge Mr Justice Royce.
He was handed a minimum 29-year prison term and an additional six years on licence in December last year.
