World Retail Congress, organised by Retail Week’s parent company Emap and due to be held in Berlin this year, has been postponed due to the chaos to air travel caused by last week’s volcanic eruption in Iceland.

The event - due to run between April 21 and 23 - will now be held on October 25 to 27 and will run with a similar programme.

The organiser said in a statement: “We apologise greatly for the inconvenience and the disappointment this causes but hope you understand the exceptional circumstances that have made this decision inevitable.”
