However, the biggest news of the day was the release of US GDP data.
David Jones, at spreadbetting firm IG Index, said: "The afternoon has been all about the USA the GDP figures released at 13:30 UK time showed that the growth in the last quarter was positive but worse than what the market was expecting.
"A revision to the final number from the end of 2007 showed that GDP back then was actually negative.
"This double whammy has raised the recession worries again for America and the numbers this time around could be said to be somewhat artificially polished up by the Federal Reserves tax rebate. The concern is that further deterioration in the housing market and overall economy is going to weigh on GDP figures later in the year, leaving todays number looking like something of an over optimistic blip. "
He added US employment data tomorrow would point to whether the FTSE would breach the 5,500 level.
