"extra £814m funding to immunisation of children in the Third World"
If, and I agree it's a big if, every penny of that goes to immunisation programmes then it's got my vote. Should be matched pound for pound by recipient countries though and deducted from their space programmes, and the like.
how many extra Muslim radicals will that money produce?
Some, probably, so your answer to Muslim fundamentalism is to see as many Muslims as possible die in infancy?
