Nick Clegg was shamed in Parliament yesterday for his tuition fees treachery as thousands of students he sold out prepared to march for free education.

Labour MPs shouted: "Say sorry" as the Deputy Prime Minister struggled to excuse his support for a funding system slammed as unsustainable by experts in a new report.

The independent Higher Education Commission (HEC) said yesterday that £9,000-a-year fees represented the "worst of both worlds" for student and taxpayers.
