Corn Laws

The most notable act of Peel's second ministry, however, was the one that would bring it down. Peel moved against the landholders by repealing the Corn Laws, which supported agricultural revenues by restricting grain imports. This radical break with Conservative protectionism was triggered by the Great Irish Famine (1845–1849). Tory agriculturalists were sceptical of the extent of the problem, and Peel reacted slowly to the famine, famously stating in October 1846 (already in opposition): "There is such a tendency to exaggeration and inaccuracy in Irish reports that delay in acting on them is always desirable".

His own party failed to support the bill, but it passed with Whig and Radical support. On the third reading of Peel's Bill of Repeal (Importation Act 1846) on 15 May, MPs voted 327 votes to 229 (a majority of 98) to repeal the Corn Laws. On 25 June the Duke of Wellington persuaded the House of Lords to pass it. On that same night Peel's Irish Coercion Bill was defeated in the Commons by 292 to 219 by "a combination of Whigs, Radicals, and Tory protectionists". Following this, on 29 June 1846, Peel resigned as prime minister.
