As a Christmas present on the 25th I just got a leaflet from UKIP in my post stating that
44% of Londoners say that cutting EU immigration would help solve the London housing crisis.
There are no references on the leaflet except for a NationBuilder based website, where you have to register (and according to the comments even after that they need to verify you and won't get access).
I tried to search for this claim but couldn't find any references where it originates from, or any additional information, like who they actually consider Londoner.
Is this claim still true?
