Queen Elizabeth II today attended a ceremony at which the Duke of York officially became Colonel of the Grenadier Guards.
Prince Andrew took over from the Duke of Edinburgh and his appointment at Windsor Castle, Berkshire, was marked by a parade.
The monarch was pictured inspecting the red-coated regiment of the British Army in the landmark’s St George’s Hall.

The queen gave her royal approval to the nomination in December last year after her husband gave up the title he’d held since 1975.
Prince Andrew joined the Royal Navy in 1979, passing out of Britannia Royal Naval College in Dartmouth, Devon, the following year.

He first joined on short-service commission as a seaman officer and sub-specialising as a pilot.
After his time at the college, the prince completed fixed-wing and helicopter flight training at RAF Leeming in North Yorkshire.
He also attended the Royal Naval Air Station Culdrose and was presented with his ‘Wings’ and the best pilot award by Prince Phillip.
King Charles II formed the Grenadier Guards at Flanders in 1656, making them his ‘Royal Regiment of Foot Guards’.

The unit is now officially called The First or Grenadier Regiment of Foot Guards to honour their 1815 victory over the French Imperial Guard at the Battle of Waterloo.
Their iconic bearskin caps – which are worn for ceremonial duty – are also sported to recognise that victory.
Guards have won 78 Battle Honours, 14 Victoria Crosses and a George Cross after serving with distinction in campaigns including the Napoleonic, Crimean, Boer, First and Second World Wars.
As well as the soft power they bring to the world stage, Grenadier Guards were deployed for ground combat in Afghanistan.
