The Air Ambulance was called after two motorcyclists collided on Llandudno promenade during a gap in proceedings at the Dayinsure Wales Rally GB.

After two days on the forest tracks of North and Mid Wales the action switched to the North Wales coast and a stage involving the Great Orme.

With the temporary grandstands packed with spectators there was thrilling action on the seafront.

But during a gap in the proceedings two bikes collided and the start of Stage 23 and the finale of the rally were delayed.

In a twitter message, rally organisers said: "Due to an incident on The Parade, Llandudno, the start of SS23 Great Orme Llandudno 2 will be delayed."

They added: "The intention is now to run SS23 Great Orme Llandudno 2 for the top competitors at 1330."

North Wales Police put out a Twitter appeal to spectators at the event: "We are currently dealing with a serious collision on the Promenade at #Llandudno which will affect the final stage of the @walesgbrally. Any witnesses or anybody who has footage from their camera phones are asked to contact us as soon as possible quoting reference number W142976" -- NWPRoadsPolicingUnit@NWPRPU

The police later said on Twitter: "We can confirm that the serious incident on the Promenade at #Llandudno involved members of the motorcycle display team and NOT a @walesrallygb competitor or a member of the public. One person has been airlifted to hospital. Our investigation is ongoing."

The rally organisers later put the stage start time back to 2pm and confirmed that one person had been airlifted to hospital.
