Edward and Andrew were seen leaving Windsor Castle after gun salutes marking Philip's death began in London, Cardiff, Belfast and Edinburgh at midday.

The duke had strong military links, including serving with the Royal Navy during the Second World War.
The Royal Family had earlier shared the Queen's moving golden wedding anniversary tribute to Prince Philip.
In a tweet, the Royal Family posted a picture of the couple and the quote from 1997, saying: "He has, quite simply, been my strength and stay all these years, and I, and his whole family, and this and many other countries, owe him a debt greater than he would ever claim, or we shall ever know."
A tribe on the remote island of Vanuatu which hailed Prince Philip as a god is expected to mark his death with ritual wailing and ceremonial dancing.
The villagers believed the Duke of Edinburgh to be a reincarnation of an ancient warrior who left the archipelago to fight a war.
Philip had maintained a respectful 50-year relationship with the tribe before his death on Friday.
