After holding ‘several high and confidential situations’ in the Company service in India,
Lushington remained in Parliament for 17 years, but his attendance was unimpressive: he suffered from gout. In July 1790 he informed the prime minister, with whom he necessarily corresponded on East Indian affairs, that he was unable to walk. On 8 Feb. 1791 he defended Cornwallis’s campaign in India and on 14 Feb. paid tribute to Warren Hastings, though he bowed to Pitt’s view that the impeachment should proceed. He was absent on 12 Apr. when opposition mustered on the Oczakov question. As chairman of the East India Company, he was created a baronet that month.
Returned for Mitchell on the interest of (Sir) Christopher Hawkins in 1796, he was equally inactive in that Parliament. As a proctor in Doctors’ Commons, he advised Pitt on the distribution of prize money and in July 1798 claimed to be ‘as attentive and full of spirit as ever’, but on 9 Apr. 1799 he was ‘at present afflicted so severely with disease’ as to hinder his work as chairman of the East India Company.
Lushington was a partner in the London bank of Boldero, Lushington & Co. with his brothers-in-law and his eldest son Henry. On 21 Sept. 1801 he approached Charles Abbot to deplore the transfer of the payment of Irish tontine annuities from their house to the Bank of England, after nearly 20 years’ agency. He explained:
I have been in three successive Parliaments, and have in the whole course of the present contest, supported government in Parliament and elsewhere, where my situation gave me more weight. I have several times been chairman of the India Company with acknowledged advantage to the public, my patronage has been extended to government and its friends ... I am ready to give any security, that may be required ... I have a private fortune of £100,000 ... clear, and independent of the banking house and property of my son and the other bankers.
Abbot replied that the viceroy had decided to take advantage of the withdrawal of Stephen Thurstan Adey from Boldero’s bank to transfer the account to the Bank of England, ‘where the other creditors of government are in the habit of being paid’.
At the election of 1802 Lushington headed the poll at Penryn, on Lord de Dunstanville’s interest. On 28 June 1803, ‘very infirm’, he was allowed to remain seated in the House to give an account of his partnership with James Heseltine, the King’s proctor, and said he was not ‘personally acquainted with every minute particular; his concerns as chairman at the India House, and director of the ... Company’s affairs having taken up a great portion of his time’. He was listed as ‘doubtful’ by Pitt’s friends in 1804 and as ‘nil’ by them in July 1805.
Lushington’s partner Heseltine died in 1804 and his office went to Charles Bishop. On 20 Jan. 1805 Lushington informed Pitt that Heseltine’s death had deprived him of ‘considerable advantages after being upwards of forty years a member of the profession’.
