A MILITARY blunder has heightened fears that the North York Moors is being lined up to play a crucial role in the controversial so-called Son of Star Wars programme.

An access road and higher perimeter fence has been built at the missile early warning base, at Fylingdales, without planning permission.

The move has been criticised by the National Park's watchdog group, the Council for National Parks (CNP), which was briefed on the error by Defence Minister Dr Lewis Moonie.

Dr Moonie provided reassurances that the Ministry of Defence (MoD) would be carrying out an environmental impact assessment and asking the North York Moors National Park Authority for retrospective permission.

According to the Minister, the commander decided to strengthen protection at the base after the September 11 terrorist attacks in New York.

"There have been many concerns about plans to upgrade Fylingdales for the United States Son of Star Wars missile system," said CNP director Vicki Elcoate.

"This incident has heightened concerns that Fylingdales could be developed by the back door, without proper public scrutiny. However, the Minister has provided reassurances and said this won't happen again which is very welcome."

The North York Moors National Park Authority has confirmed it will be considering an application for retrospective planning permission.

"It is important that the Ministry of Defence follows the proper procedures, especially in a sensitive area like a National Park," said Ms Elcoate.

"The Government is planning a change in the law so military developments are brought fully into the planning system.

"That is something we welcome as a responsible land owner, the MOD will want to be as open and accountable as it can be."
