Here you can see when it started to go wrong for the britisch economy: in mid 2010:
Hardly suprising, indeed, but for different reasons:
"Consumer spending which underpinned economic growth during the goods years, is being suppressed by falling incomes and stifling household debts. Add in the cuts in public spending, and the banks’ failure to lend money to the real economy, and it’s clear that the domestic economy is unlikely to lead us into recovery. Business investment, another potential route out of the crisis, is being crippled by a lack of confidence and weak demand (...) the biggest factor in the GDP contraction was construction. But this should surprise no-one - we already knew that domestic spending was going to be weak, that the government is cutting back investment"
This double-dip looks like a trade problem
