[1][2] At the by-election after the death of his brother Robert in 1726, Edward was returned as Member of Parliament for Warwickshire.
During the 1730s, he spoke on several occasions against the employment of a standing army and of foreign troops.
Outside of Parliament, he, like his father, was active in the Georgia Society, and served as its first chairman.
[3] On 10 July 1729, he married Charlotte Fox (d. November 1778), the daughter of Sir Stephen Fox, by whom he had six sons and one daughter:[4] After the collapse of the Walpole ministry in 1742, Digby, writing to his friend John Ward, expressed his discontent over the lack of constructive leadership on the part of the Tories, feeling the Duke of Argyll inferior as a leader to Sir William Wyndham.
The secret committee to inquire into Walpole's conduct had, he thought, been rendered nugatory through the failure of the bill to indemnify those giving evidence before it, and he was very much discontented by the machinations which brought the next ministry to power.
