Described by Horace Walpole as ‘a pale ill-looking fellow with a bent brow, a whoreson voice and a dead eye of saffron hue ... belonging to Lord Bath [William Pulteney]’,
In 1734 Limerick was defeated at Wendover, but was seated on a petition ‘notwithstanding the ministry made it their affair’ to oppose him. His petition was supported by the members of the Georgia Society, which he thereafter tried to convert into an instrument of the Opposition. In March 1739 he resigned from the council hoping ‘thereby the trustees would be induced to alter their measures, by which he meant, go over to the minority side.’ On 13 Feb. 1741 he seconded the opposition motion for Walpole’s dismissal.
After Walpole’s fall Limerick, having failed to retain his Wendover seat at the general election, was returned by the Duke of Bedford at a by-election for Tavistock. He was one of the opposition Members who were recommended to the King for seats on the new board of Admiralty but ‘demurred to accept unless more of their party were taken in, which angered the King.’ On 9 Mar. he moved unsuccessfully in the Commons for a secret committee of inquiry into Walpole’s Administration, with the result that next day the King rejected him and the other proposed lords of the Admiralty.
Till 1746 Limerick supported the Government, though in February 1744 he carried a motion against an increase in the sugar duty proposed by Pelham.

He spent the next three years in Ireland, from which he emerged to move on 4 Feb. 1751, that the army estimates be reduced from 18,850 men to 15,000.

His speeches were reckoned severe, and it was not his fault if they did not answer the character; he meant to wound but his genius did not carry equal edge with his temper.
Except for some speeches on the regency bill of 1751,
