I'm posting this link to the voting form in case anyone was unaware of it like me. The shortlist for the 2026 and 2028 sculptures includes 'Believe in Discontent' by Ruth Ewan - a black cat sculpture representing "how women from the suffrage movement would be portrayed as cats in the media as an insult." and reflecting the square's role in history. The name is taken from words spoken by Charlotte Despard, a suffragist who would often address crowds in Trafalgar Square.

They will ask your gender but if you select 'prefer to self identify' a box will appear for you to type in your answer.
