The attorney general has been urged to review a sentence given to a teenage rapist from Stoke-on-Trent.
Balal Khan, 14, was sentenced to three years in a young offenders institution at Stoke Crown Court after he admitted raping and robbing a 20-year-old woman.
Monmouth MP David Davies, a member of the Home Affairs Select Committee, said the punishment was disgraceful.
A spokesman said she was sure the attorney general would consider a referral to the Court of Appeal.
Conservative MP Mr Davies said: "Balal Khan was this week sentenced to just three years for a violent rape.
"Will you refer this disgraceful sentence to the attorney general and also investigate his parents and the community to find out how this young man could have such a complete disregard for woman's rights?"
Deputy Labour Leader Harriet Harman, standing in for Gordon Brown at Prime Minister's Questions, said she was sure the Attorney General, Baroness Scotland, would consider a referral to the Court of Appeal.
Khan was 13 at the time of the attack in Cobridge, Stoke-on-Trent, which happened last year.
