Activists from climate change group Extinction Rebellion sung Christmas carols on Tuesday evening (December 17) outside the London HQ of Shell.

The activists changed the lyrics of famous Christmas songs, including We Wish You A Merry Christmas - "don't bring us a piece of turkey" ... "alternatives to dairy are now ordinary" ... "we won't go until we get nuts, we won't go until we get fruit, we won't go until we get veg"

Lyrics of other carols urged chief executives to invest in new technology and insisted "rebelling" is a duty.
