The hon. Gentleman mentions basing the determination on needs. In last Wednesday's Adjournment debate, to which the Under-Secretary referred, there was some discussion about the system in Australia. It is based on needs, and there is a commission that makes a judgment. There is frequent argument between the federal states about the definition of needs, and some commentators are now saying that they want to move back to a per capita formula, just like the Barnett formula. Does the hon. Gentleman agree that stability might be a better prize?
