Thanks all, some really good ideas...
Basically the Tories and Whigs split over the Corn Laws, but in a different way...
Peel looses the vote in the Lords and goes to Vicky to pack thge Lords to get the Repeal Act through, but because of a lower majority (2 votes) in the commons and because she doesn't like Peel so a general election is called...
Lord Bentinck and Gladstone take basically everyone but the Peelites and some of the Whigs (radicals and the 'old whigs') to form a new 'conservative' but reforming (the introduce a embryonic 'wealthare state' funded by high traffis) party. While Peel joins the Whigs to form the Liberal Party...
I used the name Liberal-Conservatives... but I really hate the name
The Liberal-Conservatives's win the election by promising the 'wealthare state' paid for by "Johny Foreigner"

and the idea of Free Trade is effectivley killed off for a good while
Thank you very much...
