Sir William Barker, 5th Baronet

After having narrowly failed to get elected in a by-election a year earlier, Barker was returned as Tory Member of Parliament for Ipswich in a contest at the 1708 British general election where his father in law was retiring as an MP. He voted against the impeachment of Henry Sacheverell in 1710. At the 1710 British general election, he was returned again in a contest for Ipswich. He was listed among the 'Tory patriots' who voted against the continuation of the war and among the 'worthy patriots' who laid open the mismanagements of the previous ministry. He was also a member of the October Club. At the 1713 British general election, he was returned unopposed as MP for Thetford.^[3]

Barker did not stand at the 1715 general election and was out of parliament for a few years in the course of which his wife Mary died on 1 January 1716. He was returned unopposed as MP for Suffolk at a by-election on 31 October 1722. He spoke against the Government on 23 November 1724 on the army estimates, and on 12 April 1727 on the vote of credit. At the 1727 British general election he was returned for Suffolk in a contest. He spoke against the Government on 7 May 1728 on a vote of credit, and twice in April 1729 on the civil list arrears.^[4]

Barker married as his second wife Anne Spencer, widow of Edward Spencer, of Rendlesham, Suffolk, at St Marylebone Church, London, on 9 February 1731. A few months later, he died on 23 July 1731 at his house in East Street, near Red Lion Square. He was succeeded in the baronetcy by his son Sir John Barker, 6th Baronet, his only child by his first wife.^[5] He also left £500 in his will to provide for the upbringing and apprenticeship of Charles King, offspring of Mary King, who may have been his illegitimate son.^[3]
