Asquith was a "venturesome child", for example roaming the moors, climbing to the top of the roof by moonlight, riding her horse up the front steps of the estate house.

Violet Asquith wrote: "She flashed into our lives like some dazzling bird of paradise, filling us with amazement, amusement, excitement, sometimes with a vague uneasiness as to what she might do next."

In contrast, relations between stepmother and stepdaughter were frequently strained, prompting H. H. Asquith to write lamentingly of how the two were "on terms of chronic misunderstanding".

Until they moved to the prime minister's residence at 10 Downing Street in 1908, the Asquith home was a huge house in Cavendish Square in London, with a staff of 14 servants.

[6] With other politicians' wives, she attended the debate on the aborted Conciliation Bill and, in 1911, she "seemed highly amused at the earnestness" of women's suffrage lobbyists, whilst near to Constance Lytton and Annie Kenney, who remembered her as unpleasant and sarcastic.

[6] In 1912, an article in the newspaper Votes for Women told of Asquith's "stealth" journey when travelling with her husband as Prime Minister, via Wolverhampton and the Holyhead ferry, to Dublin, where the ferry was met by a yacht of Irish Women's Franchise League demanding the female vote be included in the Irish Home Rule Bill.

In 1918, she was publicly attacked in court by Noel Pemberton Billing, a right-wing MP, who was convinced that the nation's war effort was being undermined by homosexuality in high society.

[7] Billing also published a poem, written by Lord Alfred Douglas, which referred to "merry Margot, bound With Lesbian fillets".

[9] Asquith's autobiography was part of a new trend of revelatory political books written close in time to the events described, including Lytton Strachey’s Eminent Victorians in 1918, John Maynard Keynes' The Economic Consequences of the Peace in 1919 and Lord Beaverbrook’s Politicians and the War in 1928.

[10] In 1921, humorist Barry Pain published a book called Marge Askinforit, described on the cover as "a rollicking skit on the Margot Asquith memoirs".

[14] In the late 1920s, Asquith and her husband were seriously in debt: she admitted to owing £15,000 (equivalent to £1,142,000 in 2023) and having pawned her pearls for £2,000 despite, she claimed, having made £18,000 from books and £10,000 from various writings.

Asquith's autobiographical revelations about her boisterous youth and early suitors were satirised by Neil Munro in his Erchie MacPherson story, "Reminiscences", first published in the Glasgow Evening News on 8 November 1920.
