But Thomas Cook was travelling south again after Tuesday's profit warning, with the tour operator hit by the turmoil in the Arab world and economic weakness in the UK.

In the FTSE 100, Associated British Foods bucked the downward trend. It said its outlook for the full year is in line with expectations as its food arm and budget clothing retail chain Primark continue to perform well.

Silver producer Fresnillo shone following strong quarterly production figures, but other miners such as the copper producers Antofagasta and Kazakhmys are suffering.

Total sales climbed to £1.6bn from £1.45bn the previous year. Underlying pre-tax profits, which do not include foreign exchange gains and losses, exceptional costs and profits or losses on sales of investments, rose to £135.5m from £102.1m, but reported pre-tax profits, which do include these, fell to £118.8m from £119.5m.
