Vince Cable has admitted that the principle of free movement is not "defensible" because it treats Europeans more favorably those from around the world who have "more in common" with Britain.

The former the Liberal Democrat Business Secretary said he had no "theological" problem with the principle being "changed in some way."

Speaking to Radio 4 this morning Mr Cable said the principle of free movement was no longer politically viable and that migration from the EU will have to be "managed".
