Despite managing to wave to the nation on the balcony and celebrate the Platinum Jubilee - concern surrounding the Queen's health and mobility is continuing to grow.
In fact, the 96-year-old monarch pulled out of several jubilee engagements after finding the first day 'very tiring'. Just yesterday, it was reported her son and heir to the throne, Prince Charles, will stand in for her Majesty at this year's Commonwealth Games.
But with a staggering 2,000 official engagements annually, and links to around 3,000 organisations - who will step in to do the work if the Queen isn't able? The Sussexes are out of the picture, Andrew has stepped down, and Princess Anne (who attended 387 engagements last year) is in her 70s.
