Stratford City shopping centre attracted 5.5m visits during London 2012 Olympic Games

The figure is 10pc of the number of visits Westfield expects to achieve over the entire year for both its shopping centres in the capital.

The performance contrasted with other shopping areas in London - including a sister centre in west London - where retailers have complained about poor sales after repeated warnings about travel deterred non-Olympic tourists from visiting during the Games.

In the first week of the Games, footfall in the capital's usually bustling West End district, full of shops, restaurants, bars and theatres, was down 4.5pc year-on-year, according to market research firm Experian.

All visitors to the Olympic Park had to pass through the Stratford City, Europe's biggest urban shopping centre, which opened in September 2011. The centre was the subject of criticism during the Olympics after it shut for a weekend to non-ticket holders on concerns of overcrowding, Reuters reported.

"Approximately 5.5m visits were made to our [Stratford City] centre in just over two weeks, giving the group an unprecedented exposure to a global audience," Westfield co-chief executive Steven Lowy said.

The figure will account for 9pc of the company's expected 2012 visitor numbers to its two London malls. It expects both centres to attract a total 60m customer visits spending £1.8bn this year.

Westfield, the world's second-largest listed retail trust by market value, posted an improved first-half result on Wednesday thanks to a solid performance in Australia and the US and maintained its full-year outlook.
