'Queenmobile' this Royal Land Rover was used by the Queen on a visit to Northern Ireland in 1968.

To the castle... The Queen's old Bentley which still directs the driver to Windsor Castle when they tap the 'home' icon on the sat nav has emerged for sale.

The handsome Mulsanne, worth an estimated £180,000, was the personal conveyance of Her Majesty between 2012 and 2014.

During those years the motor escorted Elizabeth II to many visits in London including her only ever cabinet meeting at Downing Street in December 2012.

Although security devices and royal crests were removed from the car following the Queen's ownership the built-in sat nav was never reprogrammed.

A private collector has consigned the Bentley for auction with Bonhams, which will sell it at the Goodwood Revival in West Sussex on Saturday.

Another car that's sure to be of interest to royalist collectors is a Rolls-Royce Silver Wraith that was used as the personal vehicle of Princess Margaret.

Also included in the sale is an ex-Ministry of Defence Land Rover dating to 1968 that carried the Queen and Prince Philip during their tour of Northern Ireland on the Queen's Silver Jubilee.
