Grant, with a distinguished though controversial military career in America behind him, took with relish to the gaming tables and salons of London. Through his friendship with Henry Dundas he secured the governorship of Stirling Castle in 1789. After his unopposed return for Sutherland on the interest of Lady Sutherland two years earlier he had written, ‘I dare say, if that will do me any good, that I may be in Parliament as long as I live without having the trouble of riding a mile or writing a letter’,
He continued to support government, but is not known to have spoken in the House in this period. He voted against the abolition of the slave trade, 19 Apr.,
In 1794 George Canning, his fellow guest at the Sutherlands’ Wimbledon house, described him as
a great fat laughing old man ... a sort of Falstaff, in one part of the character at least—for if not ‘witty himself’ he is the cause of wit in others—and affords infinite room for all sorts of bad jokes, which are lavished on him unsparingly.
To illustrate his point, he related an episode in which Grant fell victim to his hostess’s talent for writing ‘sham letters’, one of which she had sent to him
as from Mr Dundas, offering him the govt. of Corsica and a red ribband, and desiring him to prepare to set out immediately—the hand and style precisely like Dundas’s—and the poor old genl. for a time in a great quandary what to think of the offer, and what answer to return to it.
