He held various roles in the household of George II (1683-1760), who was a personal friend, participated in negotiations to end the 1718 to 1720 War of the Quadruple Alliance and was British Ambassador to France from 1748 to 1754.

[11] In 2018, previously unknown records from 1746 and 1747 were discovered in Ipswich; these include intelligence reports on the search and details showing that after Culloden, Albemarle received a thousand guineas and the Prince's silver-gilt travelling canteen.

[13] They included extending the military road network begun in 1715 and placing permanent garrisons at key points, whose role was to enforce the 1746 Disarming and Dress Acts.

Although this was a decisive French victory that effectively ended the War of the Austrian Succession, his troops' disciplined fire helped the Pragmatic Army make an orderly retreat.

[15] After the war ended with the 1748 Treaty of Aix-la-Chapelle, he was sent to Paris as Ambassador, where he was a great success, entertaining on a lavish scale and sharing a mistress with Giacomo Casanova.

Albemarle died aged 52 in Paris on 22 December 1754, returning home from a pre-Christmas supper; he was buried on 21 February 1755 in Grosvenor Chapel on South Audley Street in London.

[17] Notoriously extravagant, he died leaving nothing but debts, although his sons had successful careers; in 1740, Augustus Keppel participated in Anson's capture of the Manila galleon, which made the officers wealthy men in their own right.

[18] In her biography of Madame de Pompadour, the writer Nancy Mitford remarks that given his love of all things French, it was a blessing Albemarle died before the Seven Years' War broke out.
