Caroline Criado-Perez, who successfully campaigned to put Jane Austen on the new £10 note, today launches a new campaign with Telegraph Women. Here, she explains all...

On International Women’s Day this year I spoke on a panel about the importance of women’s representation.

After the event, an audience member came up to me to ask what my next campaign would be - following my success in getting Jane Austen on the £10 note in 2014. Regretfully, I explained that I had no time for campaigning right now — earning enough money to live on was taking up all the time I had.

Then, my dog and I went for a run through central London.

We jogged along the Thames until hitting Westminster Bridge, where we turned right. Past Portcullis House. Past Parliament. Into Parliament Square. Past the statues of former Prime Minister's Winston Churchill and David Lloyd George, past military leader Jan Smuts and the 3rd Viscount Palmerston.

After the fourth statue of a man, I stopped to catch my breath and look around. Were there any statues of women at all?
