Sadly this is pretty bad news for the UK economy. There was a very bad piece of wheather but that does not really explain over a 1% move in GDP over three months. On the plus side there was a big hit from reduced Government spending and a big gain of over 1.4% for Manufacturing. As the economy rebalances perhaps we will see more of this.
One thing is for certain, there won't be any imminent interest rate rises now, as predicted here last week - albeit for different reasons.
PS The pic is that one the ONS website - shame they have not been able to update their own charts, eh?
