European stocks decreased in early trading Wednesday as markets await Troika's evaluation on Greece's progress in reducing its debt levels. The ECB, EU and IMF, collectively known as Troika, hold the key to discharging the next tranche of the bailout money, a sum of €8bn from a total of €109bn, to Greece.

Optimism about a solution weakened however following a report that European leaders were undecided about whether to reorganise Greece's bailout.

The FTSE 100 index, which on Tuesday gained significantly, fell 0.81 percent to 5,250.92, the German Dax decreased by 1.19 percent to 5,561.26, and the French CAC 40 slipped 1.28 percent to 2,984.77.
