In December 1784, Lord Temple was created Marquess of Buckingham. In November 1787, he was again appointed Lord Lieutenant of Ireland, this time under Pitt, but his second tenure of this office proved less successful than the first. Grattan denounced him for extravagance; the Irish Houses of Parliament censured him for refusing to transmit to England an address calling upon the Prince of Wales to assume the regency; and he could only maintain his position by resorting to bribery on a large scale. When his father-in-law died in 1788, Lord Buckingham succeeded him as 2nd Earl Nugent. However, since he already held the higher rank of Marquess, he was never known by this title. Having become very unpopular, he resigned his office in September 1789.
