“If you’ve been to Morocco I think you’ll understand that we’re a very colourful country, a colourful people. We see every colour being worn. In Morocco that there is the clash of colours and an attitude not to be scared of colours,” says Hassan Hajjaj. His latest exhibition, La Caravane, is about to launch at Somerset House, the first display for the British-Moroccan photographer in London in seven years. His work reflects on identity and culture, which has featured as a big part of his life and work since moving to the UK from a small port town in Morocco aged just 13.
