Silverstone has confirmed that it has not extended its contract to host the World Superbike Championship in 2014, leaving Donington Park as the sole British event on the calendar.

The iconic Northamptonshire circuit rejoined the WSBK calendar in 2010 as a replacement for Donington Park after the latter ran into financial difficulty as a result of its failed attempt to acquire the rights to the Formula 1 British Grand Prix.

With Donington Park reinstated for 2011, the two British events would run alongside one another on the calendar for the following three seasons.

However, Silverstone has struggled to maintain healthy spectator numbers compared to Donington Park and with its contract coming to an end with the culmination of the 2013 round, circuit managing director Richard Phillips has confirmed it will not be extending the agreement.

"When Donington Ventures Leisure Limited, the circuit's previous management group, went into administration in 2009, Silverstone stepped in and agreed to host the British round of World Superbikes," he said.

"However, for the last three years there have been two rounds of the championship in the UK, which has had an inevitable impact on attendances at each event. We believe it is only commercially viable to stage one round of the championship in the UK at the moment."

Having also acquired the rights to MotoGP in the wake of Donington Park's financial issues, Silverstone will continue to host the British round of the premier motorcycling championship, as well as the penultimate round of the 2014 British Superbike Championship.

"We will be focusing our efforts and attention on hosting MotoGP and the British Superbike Championship next year. We have not renewed the World Superbike contract for 2014, but there is plenty of world-class racing for bike fans to look forward to at Silverstone."
