Described in 1782 as ‘an able, experienced, and laborious man’, Beresford held places worth £3,000 p.a.
In the spring of 1801 government noted that Beresford, who was a member of the Irish secret committee, wished to retire after that session. He had to decide between his office and Parliament, being ineligible for both, and, after an unsuccessful bid in the House to exempt him from disqualification, 1 June 1801, opted in November for Parliament, with a pension of £2,000, buying a house in London to facilitate attendance. He returned to Ireland in 1802 for his re-election, which in the event was unopposed, though he had taken the precaution of being returned for Enniskillen.
Beresford apparently took little part in debate at Westminster, intervening only in favour of the Dublin improvement grant, 30 Nov. 1801, 9 Apr. 1802; on the linen trade, 30 Apr., 21 May 1802; and in defence of Irish retail duties, 3 June. He reverted to his favourite role of adviser behind the scenes. He disliked Addington’s vacillatory Irish policy and Canning regarded him in April 1802 as a Pittite at heart, pointing out that it was only for personal reasons that Beresford declined being a steward at Pitt’s birthday dinner.
Beresford probably expected acknowledgment for such services and was not averse to being appointed chief secretary on Pitt’s return to power in 1804. His name had been mentioned for it when Abbot became Speaker in 1802. The viceroy wrote to Pitt, 9 July, ‘I have no doubt at his anxiety for the office, or rather of the anxiety of his friends that he should have the offer of it’.
