Powlett throughout his parliamentary career voted with the court. He obtained from Henry Pelham at a date unknown a secret service pension of £500 a year which ceased on his appointment as lieutenant of the Tower.1Namier, Structure, 217. As a peer, he went into opposition in 1762, and was deprived of his lord lieutenancy. Together with Temple he went bail for Wilkes in May 1763; and in August 1763 Pitt, according to Grenville’s diary,2Grenville Pprs. ii. 199. included the Garter for Bolton among his terms for accepting office. Bolton committed suicide 5 July 1765. Temple described his death as a ‘heavy loss’, and wrote: ‘I wish I could say he has left many behind him whom I have so abundant reason to love, and honour, to the degree my heart felt for him.’3Ibid. iii. 70-71.
