Show this video to anyone who says there are too many immigrants in Britain

We’re all immigrants, really.

You might remember these maps from the "People of the British Isles" study, which demonstrated the genetic mix that makes up traditional “white” Britons.

Well, a new video project called The DNA Journey created by travel search engine Momondo takes a number of volunteers, and gives them a DNA test.

The video has been viewed over two million times since it was published mere days ago, and reassesses what it actually means to be an “immigrant”.

The participants were asked about their backgrounds, world views, and whether they viewed a particular culture or country as something they couldn't identify with. Almost everyone held strong opinions - and everyone was certain they knew their background well.

I’m proud to be English, my family have served and we’ve defended this country and we’ve been to war for this country.

I’m not a fan of the Germans...

The volunteers - who were from a variety of different ethnic backgrounds, including Bangladesh, Cuba, Britain and France - were instructed to spit into a tube, and their DNA sent off to a lab to be examined.

The results? Take a look below:

As one French participant who found out the largest part of her DNA is British said:

This should be compulsory. There would be no such thing as extremism in the world if people knew their heritage like that…like who would be stupid enough to think of such thing as a 'pure race'?
