A young baronet, Cotterell was a reluctant politician who represented Herefordshire’s Liberal interest for one short parliament. A loyal Palmerstonian, Cotterell singled out ‘the excellent appointments to the church made by Lord Palmerston’ for special praise.
When Cotterell stood as Liberal candidate for Herefordshire at the 1857 general election, his opponents jibed that he had deserted his ‘hereditary traditions’ and was ‘young and inexperienced’.
A lax attender, Cotterell is not known to have spoken in debate or served on any select committees while in the House. His support for religious liberty was reflected in his votes against Spooner’s anti-Maynooth motion and in favour of Jewish relief, 21 May, 15 June 1857. During his election campaign, Cotterell had refused to pledge support for the abolition of church rates, while conceding exemption for Dissenters. Once in Parliament, however, he backed Trelawny’s abolition bills.
Cotterell retired at the ensuing general election ‘entirely from a disinclination to take any prominent part in public affairs’, he informed electors.
Cotterell served as high sheriff of Herefordshire in 1865. By the mid-1870s his 5,000 acre estate in the county yielded an annual rental of £8,000.
