George Osborne has delivered the most radical Budgets in years, announcing a landmark national living wage, a host of tax giveaways for the middle classes alongside severe cuts to the welfare budget in the first all-Conservative Budget in nearly two decades.

Some of the most eye-catching of measures announced by the Chancellor were flagship policies in the Labour party's election manifesto, leading to concerns among the Opposition that the Tories are taking advantage of Labour's lack of leadership by moving on to Labour turf in their pursuit of "One Nation" Conservativism.

Surprise announcements to introduce a compulsory national living wage of £9 by 2020 and the scrapping of the permanent non-dom tax status were similar to the headline pledges made by Ed Miliband before the election.

But these announcements came alongside details of how Mr Osborne will make a staggering £9bn of further savings from the welfare budget, hitting low income families hard by freezing the top-up payments of tax credits for the lowest paid workers for four years.

In addition, the earnings level at which tax credits will begin to be withdrawn will be reduced from £6,420 to 3,850.

He also announced that families with more than two children will no longer be able to claim child tax credit on the third and successive children.

But these swingeing cuts to benefits were accompanied by a surprise announcement to raise the compulsory national living wage for those aged over 25 to £7.20 in April next year, rising to £9 by the end of the decade.

Corporation tax will fall to 18 per cent from its current level of 20 per cent in a move designed to encourage firms to boost pay as the government eyes a major overhaul of the way child poverty is measured in the UK.

The Chancellor also announced plans to speed up plans towards raising the personal allowance to £12,500 by 2020, committing the government to increasing the current rate of £10,600 to £11,000 in April next year - £200 more than was previously planned.

The middle classes will enjoy a double benefit - not only seeing their tax-free amount rising but the higher rate 40p tax threshold will go up from £42,385 to £43,000 next April.

In a blow to students from low income families, Mr Osborne announced that maintenance grants will be scrapped because they are unaffordable. They will be replaced with loans, with the maximum amount available for those from households with an income under £25,000 to rise to £8,200.

Meanwhile public sector workers will suffer further pain after Mr Osborne announced a four-year freeze in their pay.
