More tickets for the opening and closing ceremonies of the Olympic Games go on sale this week, with prices starting at �995.

The London Organising Committee of the Olympic Games and Paralympic Games (LOCOG) will release more tickets for the ceremonies, along with those for six other sports, on Friday at 11am.

The announcement of the availability of more tickets was made ahead of tomorrow’s milestone of 50 days to go until the Games.

Tickets for the ceremonies start at �995 each.

The sports for which tickets go on sale, priced from �20 to �720 each, are athletics, swimming, football at Wembley, volleyball, table tennis and boxing.

In total more than 43,000 contingency tickets will go on sale on Friday.

Contingency tickets are being released as organisers of the Games finalise seating plans.

LOCOG commercial director Chris Townsend said: “With 50 days to go there are still plenty of ways to join in and be part of London 2012.

“We are at advance stages of venue planning and these represent the final release of ceremonies and other sport tickets.

“Over the next few weeks we will release further tickets for other Olympic sports and keep people informed when tickets are available.

“We are delighted with ticket sales to date, and have sold another 1 million tickets in the last four weeks, prioritising people who were unsuccessful last time around.”

Tickets will be sold on a first come, first served basis from www.tickets.london2012.com.

So far more than 8million tickets have been sold across the Olympics and Paralympics, with around 3million remaining.
