asked the Minister of National Insurance whether European volunteer workers in the United Kingdom are treated as entitled to family allowances for their children in the same way as British subjects.

No, Sir. There is a special residence test for foreigners who have to show that they have lived here for three years out of the preceding four years before becoming entitled to family allowances.

Are these European volunteer workers entitled to apply for British nationality, if they so merit?

I presume so, but this is a purely residential test and not a naturalisation test.
