Temporary tunnels, 2m tall screens and a helicopter ride are reportedly part of an extreme plan to transport the Queen unseen to the memorial service of her late husband, Prince Philip.
As the Queen soldiers on amid news of increasing fragility, Buckingham Palace has come up with a heavily orchestrated "military-style" operation that involves a convoluted, covert journey from Windsor Castle to Westminster Abbey, according to the Daily Mail.
To get to the event on March 29, it is alleged the Queen will be flown 15 minutes by helicopter to Buckingham Palace, driven the short distance from the Palace to Westminster Abbey, then ushered behind 2m-high privacy screens and through a stadium-style tunnel - all in a bid to block the keen lenses of photographers as she exits her vehicle.
The Mail on Sunday reports that aides believe she can then be delivered into what's known as the Abbey at Poets' Corner and manage the short walk to The Sanctuary where she will be seated.
It is also alleged that she may shirk tradition and arrive ahead of the audience rather than afterwards.
