David Tennant has joined 60 high profile celebrities in a Greenpeace campaign to Save the Arctic. Right now, their photos are on display on the London Underground at Waterloo station as part of a public photography exhibition to raise awareness.

The photos - shot by world renowned celebrity photographer Andy Gotts MBE - see them wearing original t-shirts designed by fashion icon Vivienne Westwood.

Vivienne, and actress and designer Sadie Frost, were on hand to launch the exhibition earlier today.
