Bluestone supporters outside the last park authority meeting

The Bluestone development at Canaston Bridge near Narberth includes plans for 140 holiday lodges and a sports village.

Pembrokeshire Council has already given outline planning permission for the scheme which would create 600 jobs.

But some log cabins would be built on is within the Pembrokeshire Coast National Park Authority and there have been concerns raised about both their location and style.

Last month the authority whose meeting was lobbied by supporters and objectors deferred a decision on whether to give the go-ahead for legal reasons.

To leave this decision in the hands of the national park authority....would in our view result in a serious loss of public confidence in the assembly Ruth Chambers

Now the national parks watchdog, the Council for National Parks (CNP), has asked the Welsh Assembly Government to "call-in" the proposal and hold a public inquiry.

The CNP says that political pressure being placed on the Pembrokeshire park authority threatens to make a mockery of its principles.

The council's Head of Policy Ruth Chambers said the pressure was in danger of preventing a fair and impartial decision.

She said the assembly government should safeguard the planning process by making the decision itself.

"To leave this decision in the hands of the national park authority, whose members have been put under intense pressure to approve the development, would in our view result in a serious loss of public confidence in the assembly," she added.

Pembrokeshire Coast Park Authority is not now likely to consider the Bluestone plans until 19 November.

The authority had already previously deferred its decision saying it needed more time to gather information about the project.
