The 0.7 is an annualised rate, and the 0.3% for britain is a quarterly growth figure. So our growth is roughly equated at 1.2% as a n equivalent figure to the US. Plus the first quarter in recent years has been the slowest period of the year. Same last year.
Taking the figures on their own may not be looking great, but an overall growth rate for developed economies we are still near the top of the pack.
The bubble created by QE is huge though. And no-one seems quite sure what to do with it. Americans seem to be winding it in over there, but the EU is still pumping loads in as they were late to the QE party. And if you note that using QE has been a prerequisite to the economy picking up. Worked in the US, worked here, and as the EU finally started it last year so their economy is slowly picking up. Without it we could have truely had a decade with zero growth. But lets just look at the bad side of it shall we?
