It's been confirmed that the heir to the British throne, the Prince of Wales, has postponed a trip to Austria.

He was to have opened the annual Britsh trade fair in Vienna this May.

A spokeswoman said the trip had been postponed on the advice of the government following difficulties between Austria and the European Union.

Members of the EU have been imposing diplomatic sanctions on Austria ever since Joerg Haider's far-right Freedom Party joined the country's coalition government.
