A British political activist claims to have exposed leftist hypocrisy by posing as an official and asking demonstrators on a pro-refugee march to take one into their own home.

"I just noticed your placard saying 'refugees welcome here' so I was wondering if you'd be willing to go down on a list saying you're willing to take refugees into your home," Jim Boobeh asks an unidentified marcher at the event in London on June 18.

"The only problem is I rent," says the demonstrator.

Davidson moves on to several other protesters with his clipboard asking the same question and all those he interviews come up with reasons not to take in a refugee.

"Left-wing activists: do as I say, not as I do," said Boobeh of his video.

Demonstrators have been marching in recent weeks in the UK against a controversial government plan to send migrants arriving on British shores to Rwanda.

Those on the marches argue that the UK should handle migrants and refugees on British soil rather than exporting them to the African country.

Protesters holding refugees welcome here, were asked as to whether or not they would home a refugee.
