The meeting was organised by the Women's Liberal Federation and although Lloyd George was to speak it was suspected that he would avoid addressing the most important issue of votes for women. and Mary Gawthorpe The stewards tried to evict her and she pulled a dog whip. Whilst she was being evicted someone punched her chest and another burnt her wrist with a lit cigar. She featured in the local newspapers. As a result of the demonstration women were stopped from attending future talks by Lloyd George. Ogston noted her rationale for using the whip:
"a man put the lighted end of his cigar on my wrist; another struck me in the chest. The stewards rushed into the box and knocked me down. I said I would walk out quietly, but I would not submit to their handling. They all struck at me. I could not endure it. I do not think we should submit to such violence. It is not a question of being thrown out; we are set up on and beaten."
Ogston was working for the WSPU in Brighton in 1909 and speaking on their behalf in the south of England, but she became a paid organiser for the New Constitutional Society for Women's Suffrage in 1910. Ogston married twice. She married Dr Eugene Dunbar Townroe on 4 May 1912 at King's College, Old Aberdeen, Scotland. She then married Granville Havelock Bullimore on 3 January 1929 at Norwich Norfolk.
