General election 2017: All or nothing for Labour on tuition fees
Labour kept back its biggest promise when Jeremy Corbyn made his education announcements on the campaign trail on Wednesday.
Scrapping tuition fees was going to be a big statement of intent - a break with other parties and previous Labour policies, which in opposition had either proposed a modest reduction in fees, or in government had increased them.
But the manifesto leak has revealed the rabbit waiting to be pulled out of the hat.
And it shows that Labour is going for an all-or-nothing approach to university fees - asserting free education as a fundamental principle.
It's also an appeal to younger voters - with surveys suggesting that students are more likely to vote Labour.
