Government and unrestricted immigration into the UK?

A government doent released today reveals that officials made it clear that the public were against relaxing border controls, but ministers were urged to ignore those 'racist' views and go ahead with secret policies to encourage the flood of people coming into the UK. I am not racist, I'm kind of an immigrant myself and members of my family are coloured, but why do put with a political leaders who deliberately ignore us, lie to us, and consider our views (when they clash with theirs) to be racist or ill considered. In the US, Nixon was forced out for just this kind of behaviour. Why do we put up with this?
