Copeland was active in Ireland as a
Whig politician. He contested the Irish UK parliament constituency of
Coleraine at the
1831 and
1832 general elections. In 1831 the sitting member was Sir
John William Head Brydges, opposed to the parliamentary reform Bill; Copeland stood as a Protestant reformer, introduced by the local shopkeeper James Gribben. In 1832 Copeland, with continuing support from the Irish Society, was in a contest with
Sir John Beresford, 1st Baronet. On both occasions Copeland lost the initial poll, but was declared duly elected on petition. In 1834, as a dissident Whig, he supported for a time the
Derby Dilly, but ultimately gave his vote to
Lord John Russell. In the
1835 general election Copeland was re-elected MP for Coleraine, defeating Henry Richardson, by a majority of five. He sat for the borough until 1837. Copeland then contested the
Stoke-upon-Trent constituency in England, as a
Conservative candidate. He sat for that seat between 1837 and 1852 (when he was defeated) and again from 1857 until he retired in 1865. He had a period as a
Peelite, and voted for the
repeal of the Corn Laws, but after 1850 he was a Conservative follower of Lord Stanley (from 1851 the
Earl of Derby). ==Family==
