Most of what was announced in the 2012 budget was leaked in advance: a £9,205 personal tax allowance, scrapping of the 50% tax band, the introduction of a mansion tax and the cutting of child benefit.

But there were also a few things we weren't expecting: the tapering of child benefit for those earning over £50,000, confirmation that the flat rate pension will be introduced, and the levelling of personal allowances for pensioners.
