When the Queen made the decision earlier this morning that she would definitely be attending her beloved late husband Prince Philip's memorial service - military-style plans were put in place to sweep her there in the most comfortable way possible.
Earlier this month she had already missed the Commonwealth Day service at the Abbey with the decision understood to be related to her comfort travelling the 26-mile journey from Windsor Castle to London and sitting through the event, rather than a specific illness.
However, she made the journey today to honour her husband, who died last April, before making a much subdued entrance into the Abbey rather than walking the length of the building like usual.
