What are the key differences between the Liberal Democrats and the old Liberal Party?
The Liberal Party were what we would call today classical liberals. I would say they were firmly centre ground in contrast to the Lib Dems who are centre to centre-left. The Lib Dems are also europhiles, they believe in the EU project whilst the Liberal Party were soft eurosceptics.
The old Liberal Party would never have supported tuition fees.
Old liberal party members were more loyal to the UK than EU also tuition fees
The old Liberals under Gladstone were classical liberals but as the country in general fell towards socialism and the Labour Party rose, the Liberals fell to think left and were decimated post war but remained mainly of the left until the merger which in turn only came to the right under Clegg and the other orange bookers.
