Ahead of this Saturday’s ticket rush for One Direction’s ‘Where We Are’ tour, top ticket agency Viagogo claim that over 500,000 fans are likely to miss out due to the high demand.

Tickets for the tour are due to go on sale this weekend on May 25th at 9am, but the site says that demand has already been overwhelming.

A Viagogo spokesman said their data shows “over a million ticket searches by fans from Bradford to Beijing.”

They added: "With just four UK dates and an average of 66,500 tickets available per performance, the site is predicting that over half a million fans will be left empty handed at the box office.

"If everyone who has searched for a ticket so far were successful, Wembley stadium would be filled 14 times over."

The tour already has four UK and two Irish dates scheduled in 2014 as well as several across South America. Niall Horan recently took to Twitter and revealed that more are sure to come.
