In 1768 Luttrell was returned for Bossiney by Lord Edgcumbe, the seat being bought for him by the Duke of Portland as compensation for the surrender of the Luttrell interest at Wigan. In Parliament he soon became prominent by his hostility to Wilkes. According to Walpole, he had ‘a personal enmity to Wilkes’,
On 16 Mar. 1769, Wilkes was re-elected a third time for Middlesex, although he had been twice expelled and declared incapable of sitting in that Parliament; and the next day the election was declared void. It was obvious that he would again offer himself and that no other candidate stood a chance; and there appeared no end to the process of election, expulsion, and re-election. Now Luttrell, who had no property in Middlesex, offered to stand for the county if the court would support him and ensure his return on petition; and on 27 Mar. he declared himself a candidate. It was a rash and presumptuous act: for over a year Middlesex had been in a turbulent state, and few men of property in the county were willing to incur the unpopularity of supporting Luttrell. The election was on 13 Apr., and Luttrell was beaten by 1,143 votes to 296; on the 14th the election was again declared void; and on the 15th a motion declaring Luttrell duly elected was carried in the House by 197 to 143.
Luttrell, wrote Walpole,
As a reward, the post of adjutant-general in Ireland was vacated for him. But he was dissatisfied, and towards the end of 1771 threatened to resign his seat for Middlesex.
The Colonel’s expenses in his bold enterprise were yet unpaid by Government. The hero threatened, assumed the patriot, received a sop, and again sunk into the courtier.
In March 1772 he voted with his father against the royal marriage bill, probably in deference to his brother-in-law, the Duke of Cumberland. He does not appear in any other division list for this Parliament, and seems to have spent most of his time on military duty in Ireland.
In 1774 he was again returned for Bossiney on Lord Edgcumbe’s interest, but this time as a nominee of Administration. He quarrelled with his father, and refused to follow his family into Opposition. On 27 Jan. 1778 he ‘expressed his abhorrence of principles which led gentlemen to support rebellion’, and caused an uproar in the House by describing the Opposition as ‘abettors of treason and rebellion, combined purposely for the ruin of their country’.
He did not vote on Shelburne’s peace preliminaries, 18 Feb. 1783, and was classed by Robinson as a follower of North; he voted for Fox’s East India bill, 27 Nov. 1783. In 1784 Edgcumbe put his boroughs at Pitt’s disposal, and Luttrell was not returned at the general election.
Soon, however, he was trying to get into favour with Pitt. On 2 June 1785, the Duke of Rutland, lord lieutenant of Ireland, wrote to Pitt:
I shall have occasion by the next packet to write to Lord Sydney with a memorial from General Luttrell, requesting to be continued as a major-general on the future staff. His services in Parliament, and his real utility as a general officer on this establishment, are circumstances too essential for me not to become his warm advocate; and ... I must earnestly beg of you to second my application in an effectual manner.
And on 12 June Rutland wrote to Sydney about Luttrell: ‘He has rendered great services to the Government, and shown great address in some very difficult emergencies.’
Thus the way was smoothed for his return to Westminster, and in April 1786 Pitt recommended him to Lord Mount Edgcumbe for a vacancy at Bossiney. But the recommendation came too late. Mount Edgcumbe wrote to Pitt on 26 Apr., a few days before the election:
I owe I am much embarrassed, and wish I knew how to disentangle myself, for certainly I have no object in view but supporting your Administration in every way you can wish, but I fear in the present case the business is gone too far; had you been pleased to name your friend sooner, or communicated to me your intention of opening the borough, it might have been prevented, but I was so loudly called upon to name a candidate that it was impossible to avoid, and you were not in town ... Lord Luttrell’s professions of supporting Government both in England and Ireland leave me no doubt of his attachment to your Administration.
A different story was told by Thomas Orde to the Duke of Rutland on 31 May:
It is whispered to me by authority that the cause of Lord Luttrell’s failure is solely to be explained by Lord Edgcumbe, who had certainly, on his account, declined to accept the recommendation of Mr. Pitt ... I have, however, strongly impressed the opinion of its being a wise measure to seek to attach Luttrell to the Government, on both sides of the water.
And on 4 Aug.: ‘I have hinted Saltash for him, but as yet have no answer.’
He died 25 Apr. 1821.
