TUI was today battered on the FTSE 100 in the wake of the terrorist attack in Tunisia that left at least 38 people dead.

The company, which owns carriers First Choice and Thomson, shrunk by 7.10% as the investors took stock of holiday makers' willingness to travel in the wake of the atrocity.

Shares in British Airways parent International Consolidated Airlines Group fell 21.3 pence to 493.20 as the index of leading shares closed down 133.22 points (1.97%) at 6,620.48.

Discontent on the continent over Greece also continued to weigh the FTSE down after the Syriza government presented a referendum on an international bailout.

"European equity markets have collapsed as baffled traders try to comprehend Syriza's latest stalling tactic, this time in the shape of a belated referendum," said IG analyst Alastair McCaig.

He said that the public vote "smacks of Syriza shirking its responsibilities and passing the buck on to the Greek population".
