Deceitful?

Now, how do you suppose that Gordon Brown can reserve jobs for British workers? After all, he says he can. The BBC reports:

Gordon Brown is to set out measures aimed at achieving the dream of "a British job for every British worker".
The prime minister will unveil proposals to create 500,000 new jobs for British workers during his first speech to the TUC as premier.

The straight answer is that he can't. Discrimination against other EU nationals in the job market is illegal. Does Mr Brown know this? Of course he does. So why give an impression to the contrary?
