Trade issues in British politics
From the 1840s to the 1930s, free trade functioned as a primary ideological cleavage in British politics. Positioning on trade policy served not only as an economic preference but as a fundamental marker of partisan identity. The Liberal Party’s trajectory was historically contingent upon its commitment to trade liberalization. The 1846 repeal of the Corn Laws precipitated a schism within the new Conservative Party, eventually facilitating the migration of "Peelite" free-traders, led by William Ewart Gladstone, into the Liberal fold.
