British royal Prince Charles has infuriated politicians by exploiting a legal loophole to build a retreat in Scotland without planning permission.

The heir to the throne was able to erect a wooden hut in the Glen Muick hills because of an ancient right, which allows the Queen and her first child immunity to planning regulations.

But disgruntled MPs are calling for a law to close the loophole insisting the monarchy should live by the same rules as their countrymen.

Scottish Nationalist's environment spokesman RICHARD LOCHHEAD complains, "Given the chronic affordable-housing shortage and draconian planning measures brought in to protect the countryside, it's hard to understand why the Prince would be so insensitive."

A royal spokesperson says, "The Queen will be kept informed."
