My hon. Friend has put it very well. The rule is an important safeguard against abuse by those who are prepared to consider marriage as a device for securing admittance. My hon. Friend may recall that when a Labour Government were elected in 1974 they abolished the restrictions on spouses, but three years later they were so concerned about the numbers coming in that they introduced the marriage of convenience test, which is the forerunner of the primary purpose rule. I am disappointed that Labour now wishes to repeal that rule.
