Descended from the seventeenth century poet and politician, Waller owned estates near both Great Marlow and Chipping Wycombe, carrying considerable influence in both boroughs. As a youth of 21, he was used by Aislabie (his stepfather and father-in-law) as a cover for his own speculations in South Sea stock. The facts came out when the South Sea committee of the House of Commons, on examining the books of the Sword Blade bank, found entries totalling nearly £800,000 representing Waller’s stock exchange transactions between March and November 1720, with a credit balance of £77,000 due to him in respect of these transactions. On further investigation it transpired that £33,000 of the £77,000 admittedly belonged to Aislabie, who himself is reported afterwards to have said that the correct figure was £53,000.
Returned as a Whig on the family interest at Marlow, Waller helped his brother, Harry, to capture Wycombe in 1726, spending more ‘to get one borough than would buy a score’.
On Walpole’s fall Waller was offered a seat on the Treasury board but ‘refused until the whole party were agreed and satisfied in the measures to be pursued’.
In the next Parliament Waller was classed by the Government as Opposition and by the 2nd Lord Egmont among the Prince’s supporters, which did not prevent him from applying to Newcastle for a company in the army for his eldest son.
Horace Walpole describes Waller as
a dull obscure person, of great application to figures and the revenue, which knowledge he could never communicate. He spoke with a tone which yet was the least cause of the unintelligibility of his speeches. Lord Chesterfield went for six weeks to his country house to be instructed in the public accounts, and when he came back said he had been beating his head against a Waller.
