All Coast Guard boat operations have been suspended with immediate effect following concerns over lifejacket safety.

The Irish Coast Guard's shoreline and cliff rescue services remain in place, along with its four rescue helicopters.

While boat operations are suspended, the affected areas will be serviced by the RNLI, community rescue boats, and the Naval Service.

Earlier, the Irish Coast Guard said in-shore rescue boats in 23 locations around the country were withdrawn from service amid concerns over lifejacket safety.

It said it is confident the issue can be resolved quickly. 

Rescue 400 lifejackets are affected by the issue.

The problem relates to one specific section of the jacket, which failed to fully function when activated.

The RNLI said the type of lifejackets it uses is different to the lifejackets used by the Irish Coast Guard crew and its lifeboat service is unaffected by this issue.

The RNLI has 46 lifeboat stations around the country and remains on-call.

An investigation is now under way into the malfunctioning lifejackets.
