Sharp was ‘bred to trade from infancy’
Sharp set out in politics as a dissenting radical, a member of the Society for Constitutional Information (1788) and promoter of the Friends of the People (1792). In 1802 he visited Paris and doffed his hat to Napoleon.
Sharp was urged by Henry Brougham to assist the Whig press attack on the new ministry, if possible to write ‘a separate tract’ and to rally his literary friends. When he was ousted from the finance committee by the ministry, 30 June 1807, he had the satisfaction of hearing Henry Bankes deplore the omission of ‘one of the most active, the most eminently useful servants to the public’ and of seeing his replacement by Hugh Leycester become a matter for a division of the House. He himself warned ministers that he was in possession of ammunition to use against them and assured his friends, ‘The ministry must be licked up’. To this end he was prepared to support the plan for national defence devised by Lord Sidmouth’s friend Lord Selkirk and to promote its adoption by the city of London under the aegis of (Sir) William Curtis, though his Whig attachments prevented him from doing so publicly.
Sharp’s parliamentary fate was decided by his motion of censure on ministers for the Copenhagen expedition, 21 Mar. 1808. He had given notice of it on 8 Feb. and had meanwhile (10 Mar.) ridiculed the City supporters of the orders in council. His set speech of censure dwelt on the moral shortcomings of England’s treatment of Denmark. He was urged to publish it, but his motion was heavily defeated (224 votes to 64). Thereafter he never cut a figure in debate, though he voted steadily with the moderate Whigs and was present at their meeting to endorse Ponsonby’s leadership, 18 Jan. 1809. On 15 June 1808 he dissociated himself from a debate on the exemption of foreigners investing in the funds from taxation. He criticized the lack of progress of the remodelled finance committee, 24 Jan. 1809. He himself gave evidence for their fourth report on prize commissions, 24 Feb. He objected to government interference by bounty to encourage flax growing in Ireland, 22 Mar. 1809. He blamed ministers for the crisis over (Sir) Francis Burdett, 9 Apr. 1810. He gave up a motion on the exchange of prisoners of war pending current negotiations, 4 May. He voted for parliamentary reform on Brand’s motion, 21 May, though he could not be rallied to the extra-parliamentary meeting to promote constitutional reform in the following year. He failed to secure a debate on the proposal to create a new naval arsenal at Northfleet, 5 June 1810. He was a member of the bullion committee and defended their report, 8 May 1811; also a member of the committee on commercial credit. He regularly supported sinecure reform and Catholic relief. In February 1812 he was an intermediary in the flirtation between Canning and the Whigs, and in April between Canning and Grattan, the Catholic champion.
Sharp was left without a seat in 1812, Lord Cholmondeley being a friend of the Prince Regent. He was invited to contest Great Yarmouth, Lewes, Evesham and Coventry and might have been tempted by the latter ‘on account of the public grounds on which he had been asked’, but for the expense and his expectation that the Parliament would be a short one. His friends looked out for a vacancy for him.
Sharp signed the requisition to Tierney to lead the opposition and on 2 Feb. 1819 voted for his motion for a committee on the Bank. Soon afterwards he vacated his seat to let in his friend David Ricardo. He had been defeated in a contest against Lord Anglesey’s interest at Milborne Port at the general election. In July 1819 he was again unsuccessful at a by-election there. Nor did he succeed in the election of 1820, when he contested both Milborne Port and Maidstone. He was unseated after his return on Lord Darlington’s interest in 1826. His later years were devoted to literature, society and his annual visits to the Lake District and the Continent. He died 30 Mar. 1835 leaving a quarter of a million, much of it to his adopted daughter Maria Kinnaird.
