The deputy prime minister has given his permission for the "auto-tune" version to be issued by satirical website thepoke after it received thousands of views.
He has requested all profits be given to The Children’s Hospital Charity, who support the work of Sheffield Children's NHS Foundation Trust. The official version, in which Mr Clegg apologises for the Lib Dems breaking their pre-election pledge not to raise tuition fees, is to be officially broadcast at the party's autumn conference.
The party leader apologised for breaking his party's election promise once in Government and has defended the decision to "leave the comfort of opposition" and forge a coalition government with the Conservative Party.
In a party political broadcast, due to be aired nationally on Monday, the Sheffield Hallam MP apologises for making a pledge on university tuition fees that he was unable to stick to.
