Peston: All eyes on eurozone
Instability on the stock markets has continued, despite better-than-expected US jobs figures.
There have been sharp falls in the past 24 hours amid a crisis of confidence due to the eurozone debt crisis and concerns about weak economic recovery in the US and Europe.
A fall in the US jobless rate caused the US markets to open higher and gave temporary relief to European indexes.
But London's FTSE and Frankfurt's Dax were soon down about 2% again.
"A crisis for the eurozone would be a very serious problem for the UK", explained the BBC's Business Editor Robert Peston.
