Extra resources have been brought in to help in the search for a missing kayaker.

Alistair Collier has not been seen since he started a race between Knoll beach and Swanage yesterday.

A major search operation has been launched to find him.

Today, the HM Coastguard fixed wing aircraft is being brought in to assist.

Organisers raised the alarm early yesterday afternoon after the man failed to finish the race which was running between Knoll Beach and Swanage Pier.

An extensive search was carried out yesterday and overnight with lifeboats from Swanage, Poole, Yarmouth and Weymouth, along with Coastguard Rescue Teams from Swanage, St Albans and Lulworth. Coastguard helicopters from Lee-on-Solent, St Athan and Newquay were also involved in the search overnight.

This morning coastguard rescue teams from Swanage, St Albans and Lulworth continue to search along with lifeboats from Swanage and Bembridge, Dorset Police and the fixed wing Coastguard aircraft.

Duty commander Mark Rodaway, OBE from HM Coastguard said: "We are continuing to search for this kayaker.

"There has been no sign of him or his kayak since yesterday afternoon and we’re obviously very concerned for him.

"The search will be extended this morning to other areas to allow for the time that has passed and the possibility that he may have got to safety somewhere else."
