It is ironic that Mrs Patel being a native of the Indian sub-continent should be against further immigration :-)
I agree that it is ironic that they quoted Mrs Patel, who is probably 2nd or at the most 3rd generation British. However, the fact that they did gives a much stronger message than speaking to (yet another) white British person and asking for their views on immigration.
Someone like Mrs Patel speaking on such an issue is similar to her speaking into a microphone, while the rest of us yell at the top of our lungs into the middle of a hurricane......and at best get ignored, or at worst get dismissed as having a racial motive.
However the bloke who wouldn't "work with a load of foreigners" for £7 an hour needs his backside kicking from here to eternity. Lazy, ignorant bar steward !!!
