Many have been shocked by the news that the Conservatives will be breaking their manifesto pledge not to raise National Insurance.

Those who follow the Conservative Party's official press Twitter account will be even more flabbergasted, as they vehemently promised 20 times not to raise the tax.

Under David Cameron and George Osborne, especially around the 2015 General Election, they said what set them apart from Ed Miliband and the Labour Party was their promise not to raise taxes such as National Insurance.
