Curious onlookers examine a series of giant sculptures in Victoria Tower Gardens, next to the Houses of Parliament in Westminster. The work of Mexican artist Rivelino, ‘Nuestros Silencios’ (Our Silences), will be on display until 11th February. The 10 giant bronze busts each weigh over a ton and are being displayed in London as part of a European tour celebrating the bicentenary of Mexican independence and the centenary of the Mexican Revolution.
