... the Coalition's immigration cap will, as anyone with even a passing knowledge of immigration politics knows, will do absolutely nothing to return the rate of in migration to the UK to the halcyon days of Thatcher, or at least that's what the Home Affairs committee is currently saying. Yes, even their modest desire to return to 1990 levels, whilst seeking in most other areas to take the country back to Victorian era values and standards, is doomed to fail.
It always was a 'pie in the sky' idea* and as the committee point out the only way it would be achievable would be for Britain to withdrawn from the EC, close down most of the universities in the country (it is only the revenue from foreign students that keeps most of them afloat), risk social unrest by ending the right of those already granted leave to remain in the UK to bring members of their family (spouses and children) to the country. Better think again about the defence review and start stationing those gunboats of the Channel coast Dave™.
* Still it quietened the frontline party troops during the election campaign.
