Poyntz, whose marriage had brought him a substantial estate in Sussex centred on the ruined mansion of Cowdray, was described by the local historian as ‘a remarkably handsome man, very tall, and with a clear and bright complexion’.
He voted with the Whig opposition to Lord Liverpool’s ministry on all major issues, including parliamentary reform, 24 Apr., 2 June 1823. He divided for Catholic relief, 1 Mar., 21 Apr., 10 May 1825. He decried the ‘unconstitutional severity’ of the game laws and ascribed the prevalence of poaching to the ‘miserable pittance’ paid to labourers, 2 June 1823. He sympathized with a publican who had petitioned the Commons on being refused a licence by Chichester magistrates, 31 May 1825, but denied the inference of corruption.
He divided against the grant to the duke of Clarence, 16 Feb., and for Catholic relief, 6 Mar. 1827. He voted against increased protection for barley, 12 Mar., and for the spring guns bill, 23 Mar. On 9 May he warned that the bill to transfer Sussex elections from Chichester to Lewes would give excessive power to the voters of Brighton, who though ‘respectable persons’ had ‘no claim to choose a Member for the agricultural county of Sussex’.
And so they are all out. Heaven be praised; an Ultra Tory administration excepted, anything must be better ... than going on as we have since March, deluding the country by an imaginary government, and letting the k[ing] run riot in the manner he has. As our friends have seen that vacillation and want of firmness do not succeed, I hope they will now try the other extreme. I hear the duke of Wellington will if possible include Peel in the new arrangement, but I cannot think he can form a Tory administration.
In passing this letter to Lord Holland, Tavistock observed that it contained ‘precisely the sentiments which I hear amongst all classes’, though he claimed that at an earlier stage Poyntz had been well disposed towards the coalition ministries.
He was soon returned to the Commons on a vacancy at Ashburton, engineered by his son-in-law Lord Clinton, in February 1831.
Poyntz was returned unopposed for Ashburton at the general election of 1832 and later sat for Midhurst, where the Cowdray estate gave him an interest. While out hunting in 1836 he fell and damaged his spinal cord, which rendered him subject to fainting fits. He died in April 1840, after ‘four years in constant suffering’, and his daughters sold the Cowdray estate to the 6th earl of Egmont.
