First, it is quite difficult to set out immigration policy in primary legislation. That is why this Bill is drafted as it is. I have, as I say, some sympathy with the Scottish National party in the House of Lords in saying that this is really very wide. We would like to see something pretty close to the existing tier 2 system, with a salary threshold of the order of £30,000, and the shortage occupation list developed. I think that can deal with a number of problems; it already does nurses, and it could do laboratory assistants, for example. We favour the seasonal agricultural workers’ scheme, which has just been mentioned. We suggest that the way to deal with the lesser skilled—if I may use the term, meaning that middle group—is to have temporary visas for semi-skilled workers, limiting them to three years and having an escalating annual cost of £1,000, £2,000 and £3,000, so that there is a financial incentive for employers to train their own people. For the past 10 years, the training of apprentices and so on has gone through the floor, and it has done so because you can take a plumber or whatever from Poland without bothering to train them. We need to make sure that there is a financial incentive for employers of these skills to train British replacements.
