Congratulations to Her Majesty The Queen and the Duke Of Edinburgh, who today are celebrating their Blue Sapphire wedding anniversary.
The landmark anniversary, which only one of around 2,000 couples in Britain will celebrate this year, will be marked privately by the royal couple.
The Queen is the first British monarch to commemorate her 65th wedding anniversary, adding yet another milestone in her Diamond Jubilee year.
After attending the Royal Variety Performance in London yesterday night, the Queen and the Duke are said to be 'marking the day privately' by a palace spokesman, before carrying on their duties for the rest of the week which include a join visit to Bristol on Thursday and official engagements for the Duke on Friday as well.
