Despite a 25 per cent devaluation of sterling, UK exports to Asia in the last three years have grown at a slower rate than those from Greece and Spain. In 2011, per capita gross domestic product in Ireland was greater than that in the UK. Meanwhile, the role of the state in the UK economy has grown and taxes have risen.
…More generally, individual risk and effort is not rewarded when the UK government share of GDP has risen from 38 per cent in 1999 to 51 per cent in 2011, the effective top rate of tax is over 50 per cent, and CPI inflation for the last five years has averaged 3.5 per cent.
That is from MP Liam Fox, more at the link. Elsewhere (gated, at The London Times) I have written that the UK is especially vulnerable to The Great Stagnation.
