Six thousand increase, for most universities (was 3k, now 9k). The previous fee increase, which took place in 2006, was a similar percentage rise. Tuition fees were trebled from just over 1k a year to 3k.
And, yes, there are many British students who feel the same which is why we had the student protests in 2010.
Some of these protests got a bit out of hand and led to vandalism and riots, resulting in a small number being arrested and given prison sentences.
http://en.wikipedia.org/wiki/2010_UK_student_protestIt's not the result of the Eurozone crises, if that's what you mean. The Eurozone crises is something separate and the UK is not part of the Eurozone though it still affects the UK - as the Eurozone countries are major trading partners.
The financial crisis of recent years has been worldwide, and isn't limited to the Eurozone or wider European Union.
The free increase was the result of the Browne review, a study commissioned by the (then) Labour government. In late 2010 it published its findings which included a recommendation that the cap on tuition fees be removed. Effectively this would create a market system, whereby universities could chose whatever they felt they could. This was partially rejected by the Conservative-Lib Dem coalition government, which took over from Labour after the 2010 General Election. Although they didn't agree with uncapped fees, they did raise the cap from just over 3k to 9k.
It should also be said that those resident in Scotland can study at Scottish universities for free. Also those living in NI (and go to Northern Irish universities), or those in Wales (going to Welsh universities) don't pay the full 9k.
Students from the other EU countries will pay whatever a person from that country pays. So will also pay no fees in Scotland, and the lower fees in Wales and Northern Ireland. Only in England will EU students face fees of up to 9k.
