The FTSE has fallen steadily this afternoon as investors failed to take confidence in strong Q1 results from Barclays.
At around 4pm, the index was down 1.12%, losing 62.72 points to 5,555.12.
Barclays was the biggest faller, shedding 6.35%, or 22.95p, to stand at 338.3p per share.
This was despite the bank posting a £1.82bn profit for the first three months of the financial year, up 47% on a year earlier, with most of it coming from investment banking arm Barclays Capital.

The blue-chip banking giant took the hit after news its income from investment banking dropped markedly year-on-year to £3.8bn from £5.2bn, which overshadowed a 90% leap in underlying group profits.
Banker Lloyds also suffered, losing 2.35p per share, or 3.46%, to 65.65p a share.
Miners made up the rest of the top five losers.
Shares in Rio Tinto tumbled 4.43%, or £1.56p, to £33.76 per share, likewise Xstrata shares lost 43.50p, down 3.84%, to £10.89p a share.
Stocks in Vedanta Resources were down 3.47%, losing 91p, to £25.34 per share.
Elsewhere, the Dow Jones was also slightly down, losing 16.7 points, or 0.15%, to
