Go for a wander around Parliament Square and you'll see statues of Mahatma Gandhi, Nelson Mandela, and plenty of former Prime Ministers including Winston Churchill and David Lloyd George. Noticing a theme here? Yep, they're all men. In fact, there are 11 statues in Parliament Square and not one of them is a woman - and now activists are calling on our new London mayor to do something about it.
Feminist campaigner Caroline Criado-Perez has written an open letter to Sadiq Khan asking him to put a statue of a suffragette in Parliament Square by February 2018. The proposed date would mark 100 years since women were granted the right to vote. The letter has been signed by some high-profile women, including Emma Watson, JK Rowling, Caitlin Moran, Bridget Christie and MPs Jess Philips, Caroline Lucas and Stella Creasy. You can get involved with the campaign by signing the petition on change.org, which has already received more than 68,000 signatures.
