Following the split in the
Tory Party over the
Corn Laws in 1846 and the consequent end of Sir
Robert Peel's
second government, the
Whigs came to power under Lord John Russell. Sir
Charles Wood became
Chancellor of the Exchequer, Sir
George Grey Home Secretary and
Lord Palmerston Foreign Secretary for the third time. One of the major problems facing the government was the
Great Irish Famine (1845–1849), which Russell failed to deal with effectively. Another problem was the maverick Foreign Secretary Lord Palmerston, who was eventually forced to resign in December 1851 after recognising the
coup d'état of
Louis Napoleon without first seeking royal approval. He was succeeded by
Lord Granville, the first of his three tenures as Foreign Secretary. Palmerston thereafter successfully devoted his energies to bringing down Russell's government, leading to the formation of a
minority Conservative government under
Lord Derby in February 1852. ==Cabinet==
