George Osborne has announced that child benefit will be withdrawn from higher rate taxpayers from 2013: Child benefit . (Incidentally, one would think the Telegraph would know the difference between 'principal' and 'principle').
Universal benefits of this kind cost a huge amount of money, although they also underpin support for the welfare state from the better off part of the population.
Of the various options that have been discussed so far, this is a more equitable move than stopping child benefit at 16 or restricting it to the first two children (the latter would particularly hit poorer families).
It will be interesting to see whether there will now be restrictions on the winter fuel payment or bus passes. One has to remember that a lot of older votes are Conservatives and they have a high rate of turnout.
