Mixing the blood of thousands: Artist Marc Quinn on his most ambitious project yet

It is the artist Marc Quinn’s most ambitious project to date. And that’s saying something.

Because this is a man who came to prominence after filling a cast of his head with ten pints of his own blood.

Now he’s aiming to repeat the trick – this time in collaboration with refugees.

The aim is to raise awareness – and cash – to support their plight.

“Our Blood” mixes the blood of thousands of people – half of them refugees.

Fatima Manji has been to meet him at his studio.
