Conservatives
Cameron promises to give the Welsh Assembly more powers, including being able to call itself a Parliament and being able to raise its own income tax. Interesting for G and P students in unit 1 considering how Cameron has changed the Conservative party since the days of Thatcherite concentration of power in Westminster.
Labour
Miliband promises to lower tuition fees for University students to £6k from its current £9k. Again - interesting to consider how this fits into the narrative about the Labour party and its move away from / back towards more left-leaning policies.
The BBC's Robert Peston analyses the fiscal implications of all of this here.
