London 2012: More Olympic tickets to go on sale

More tickets are to go on sale on Wednesday for events at the London 2012 Olympics - with anyone eligible to buy a ticket.

There are some £20 tickets left for sports such as volleyball, table tennis, weightlifting, taekwondo, boxing and fencing.

But several sports have sold out, and there are only higher-priced tickets left for most medal events.

The tickets will go on sale from 11:00 BST for 24 hours.

Their availability can already be viewed on the website.

Organisers Locog say there is a good number of tickets at the cost of £45 to £450 in sports including archery, badminton, basketball, beach volleyball, canoe sprint, diving, handball and hockey.

Only a limited amount of tickets are available in race walk, mountain biking, artistic gymnastics and rowing.

Up to four tickets can be purchased per session, and up to four sessions in one transaction, for all available sports apart from football - where more tickets are available to encourage groups to attend.

All tickets have been sold in some sports, including athletics, cycling, equestrianism, rhythmic gymnastics and swimming and the opening and closing ceremonies.

Locog commercial director Chris Townsend said: "Our priority has been to get as many people who missed out in the sales process last year to the Games.

"We have delivered on our promise and now another 150,000 people have successfully purchased up to four tickets each."

He warned: "Wednesday's sale is a live sale, and, like other high demand events including pop concerts, we expect the website to be very busy and customers may well be held in queues for over 30 minutes at peak times".

The online ticketing system sparked criticism last year after it crashed under high demand.

In some cases, the system reportedly informed potential buyers they had secured tickets, who were later told that they had failed.
