You do know the Crown Estate also looks after all the beaches around the UK
They issue paid for leases and licences for various activities and enterprises.
They'll let you organise beach cleanups without formal permission though.
Parliament and loads of Government Buildings in London are RENT FREE
Well you wouldn't expect the government to pay itself rent. Only the future king manages this bit of creative accounting although his brothers have managed very sweet leasing deals on their palatial abodes.
the Crown Estates pay for the Entire MP salaries as was the Agreement . This would cost Billions to cover
The agreement was that the income from the Crown Estate was handed over to release the royals from the financial burden of the entire costs of running the country. Excellent deal for them.
You do know that any NEW Monarch within days of becoming King/Queen signs to say they are willing to let the Crown Estates continue to be managed by the Government and not revert back to the Crown
Of course they do. See above.
Also rather a lot of people have to die before Andrew could get his hands on a Crown!
But for an accident of birth order we'd be looking at the future coronation of King Andrew right now and nothing to be done about it.
