In 1908 Leigh, Jennie Baines, Lucy Burns, Alice Paul, Emily Davison and Mabel Capper were arrested for trying to stop a Limehouse meeting on the Budget by Lloyd George.

On 17 September 1909, she, Charlotte Marsh and Patricia Woodlock climbed onto the roof of Bingley Hall in Birmingham to protest at being excluded from a political meeting where the British Prime Minister H. H. Asquith was giving a speech.

[citation needed] On 18 July 1912 in Dublin, she threw a hatchet at Asquith, hitting instead Irish nationalist leader John Redmond who was injured.

[3] On 13 October 1913, at the Bow Baths in the East End of London, Leigh was hurt when police were hitting women and men protestors with clubs, according to Mrs Pankhurst.

Pankhurst had agreed that the WSPU would suspend its militant campaign for female suffrage and back the government's fight against Germany.
