In 1822 Heygate, who coveted a baronetcy, wrote to Lord Liverpool describing himself as ‘possessed of an adequate property, landed and otherwise, as well in possession as reversion and ... I am descended from a family which declined at its first institution the title of baronet for reasons which did them no discredit’.
Chosen a common councilman for Cripplegate Within in 1809 and an alderman for Colegate Street in 1812, and prominent as a Merchant Taylor and company director, Heygate was also a founder member of the Hampden Club to promote parliamentary reform. He was invited to contest the London by-election of 1817 on a moderate Whig platform, but declined. He promised (10 June) to offer at the next opportunity,
On 25 May 1819 Heygate opened the adjourned debate on the resumption of cash payments, having failed to secure a hearing the night before. John William Ward remarked to Bishop Coplestone:
The anti-bullionists are too much overmatched to make any fight. You see they had nothing for it but to put forward Alderman Heygate as their champion ... It is not a very good subject for debate. It is too scientific, and consequently far better fitted for writing than for speaking.
Ward, Letters to Bishop of Llandaff, 223.
Heygate criticized the composition of the secret comittee, which had examined ‘but one country banker’. He disliked the Bank restriction in principle, but objected to the proposals for lifting it: they would find the money market ill-prepared and might start a panic. He was a diehard opponent of the cash payment bill, 14 June. He also voted against the foreign enlistment bill, 3 and 10 June, and the excise duties bill, 25 June.
Heygate took his own line on the government’s repressive measures in December 1819. He voted to limit the duration of the seditious meetings bill to three years, 6 Dec.; voted against the seizure of arms bill, 14 Dec.; supported the blasphemous libels bill, 23 Dec., but tried in vain to have it limited to three years, and spoke ambiguously on the newspaper stamp duties bill, 27 Dec., attributing the economic depression to the ‘great diminution of the currency’. He died 28 Aug. 1844.
