Child benefit changes take effect

More than a million better-off families will lose some or all of their child benefit, under changes which have come into force.
Families with one parent earning more than £50,000 lose part of their child benefit, and it will be fully withdrawn where one parent earns above £60,000. The government hopes to save £1.5bn a year to help reduce the deficit.
David Cameron described the move as "fundamentally fair", but Labour said it was a "huge assault" on families.
