According to the UK Independence Party website UKIP will try to achieve the following if they gain power at the 2010 general election:

UKIP fully supports the British Monarchy and its Constitutional role. We oppose disestablishment of Church, and believe the Monarch should remain Defender of the Faith. We would restore public oaths of allegiance to the Monarch not the State, reflecting the constitutional role of the Monarchy in the UK and the danger of elevating the authority of the government further. UKIP will consider a transfer of part of the Crown Estates back to the Monarchy, in exchange for an end to annual State support.

I would be interested to hear both positive and negative views on UK Independence Party’s The Monarchy policies in the comments below?
