More importantly is this take from Linda Jack

As a Lib Dem party member who has called for Nick Clegg to apologise for us breaking our pledge on tuition fees, my first reaction last night was to welcome his public mea culpa. But listening carefully to what he had actually said, it became clear he was making the wrong apology. As Julia Hartley-Brewer pointed out on Twitter last night, “Nick Clegg’s apology for breaking tuition fees pledge is like a husband saying ‘sorry for my affair, next time I won’t vow to be faithful’“. What students, voters and members were angry about wasn’t us making the pledge in the first place, it was us breaking it.
