Nick Clegg watches auto-tune spoof apology video
Liberal Democrat leader Nick Clegg joined Andrew Marr in watching the musical spoof of his apology over tuition fees and explained how money raised from it will go to charity in his constituency of Sheffield.
The video has already become an online hit and re-edits the deputy prime minister's apology, made ahead of the Liberal Democrat conference in Brighton, auto-tuning his words to fit a backing track.
