claig .... in 1979 when the Conservatives inherited horrendous taxes across our economy, they began to fall, but not always in a straight line, as we had other factors along the way e.g. a 1991 European recession, but always as a 'direction of travel' lower, so if you compare 1979 to 1997 tax rates it would blow your Soviet socks off.
As to your link, not only is it a bit vague taking an overall increase of taxes on the whole economy when reducing a deficit, I'd suggest that while obviously searching for a headline, using a March 2015 article when there has been I believe a UK Budget and Autumn Statement since then, it won't be up to date.
Having said that the IFS says that this recent Tax Credit policy will make the poor worse off, it seems to be unclear to me if the figures include ALL the tax cuts since 2010 e.g. the lifting of the personal allowance from over 6k to around £11k, and how it will look when the Minimum wage goes up.
The alternative to a 2010 Conservative administration was a 4th term of Labour who stated that they would cut LESS of the deficit, and tax MORE as the 'taster' below showed;
(2010) “Labour’s plans to increase national insurance next year will cost jobs, Alistair Darling has said.”

But of course when Labour keeps dumping taxes on the poor, like Council Tax up 105% on average in England on a Band D property over 13-years mostly through a tax receipt boom, its always done with love.
claig .. you really needs to stop fixating on a buzz word and try to build a case around it, as trying to show Cameron/Osborne as non real Tory 'modernizers', will lead you to a hiding to nothing.
As on the fat state/weak business structural Road to Greece, the UK economy needed rebalancing, and Pay needed rebalancing from HIGH Taxes, HIGH credits, LOW pay, to the opposite - and going through a much needed transition which could be useful whether the global economy tanks again or not.
There is no doubt that the core Conservative tax/spend model is being implemented, after all, if there was any doubt that it is the least sustainable type of economy, the last 13-years of Labour proved the state cannot be bigger than the economy £££ supporting it.
