The TaxPayers' Alliance is accusing the Chancellor of double standards as its report reveals he has repeated the 'endless tinkering' of the tax system by the Labour government, despite being a vocal critic of such tax policy.

According to the report, more than twice as many taxes have been introduced into the UK tax system than have been cut, since the coalition took power, and the amount of tax brought into its coffers by 2015 will be 15% higher than the final year of the previous government.

The body that campaigns for reduced taxes has calculated that while the ConDem coalition had already removed or reduced 109 taxes since coming into office, 254 taxes have either been introduced or increased.

The report goes on to show that while the previous Labour government, in 2009/10, had collected £513bn (or £549 billion at 2012/13 prices), the current leaders of the nation will have increased that amount to £671bn (£633bn at today's prices).

Matthew Sinclair, chief executive of the TaxPayers' Alliance, said: "Endless tinkering at the edges of the tax system was a vice that George Osborne criticised in the last government, but of which he is equally guilty now he is in office. Many of the coalition's hundreds of changes create just as many new complications as they resolve and every one will have affected long term investments, often in quite subtle ways. That creates uncertainty which will undermine economic growth. Britain needs more lasting, strategic tax reform and less fiddling at the margins."
