The Queen has been staying at Windsor Castle recently – the Court Circular has been datelined from there; a Privy Council was held at Windsor on Wednesday. But on Tuesday Her Majesty travelled to London so that Gordon Brown could meet her at Buckingham Palace to ask for the dissolution of Parliament.
I wonder how usual it is nowadays for the Queen to travel at her prime minister’s convenience. Things were certainly different in Queen Victoria’s time; cabinet ministers were constantly having to go down to Windsor or even Osborne House to transact official business with the Queen, & a duty minister had to be in constant attendance at Balmoral.
