At the 1820 general election De Crespigny offered again for Southampton, where George Tierney, the Whig leader in the Commons, feared that his seat was ‘in jeopardy’. After a seven-day contest forced by a ministerialist he was returned at the head of the poll.
De Crespigny endorsed a petition against the ‘obnoxious’ Irish window tax and demanded its abolition both there and in England, 25 Feb. 1822. He spoke for an amendment to government proposals for the reduction of navy five per cent stocks, proposing that more time be allowed for dissent to be heard, 8 Mar.
De Crespigny’s only known vote of 1824 was for repeal of the assessed taxes, 10 May, though he spoke occasionally. He asked ministers whether they intended to increase the size of the army, 4 Feb., receiving a qualified positive answer, and urged moderation in the West Indian army estimates, 20 Feb.
At the 1826 dissolution De Crespigny, who had been widowed in December 1825, retired on account of ill health, citing ‘palsy and apoplexy’ in his parting constituency address and likening himself to a dying swan on the hustings.
