The ban of flight passengers carrying liquids in hand luggage will be lifted within three years.

The announcement came yesterday from the European Commission which said European airports will have to install technology which can detect liquid explosives.

The ban on liquid containers larger than 100ml has been in place since an al-Qaeda plot was uncovered in 2006 to blow up planes with liquids in soft drink bottles.

Commision vice-president Siim Kalla said: “A lot has been learned since the first EU-wide rules on aviation security standards were put in place after September 11.

“This is about building on the experience of recent years and streamlining procedures so that security measures are easier for the industry to implement.”

The ban will be lifted by April 29, 2013, at the latest.
