The Watford Observer would like to wish Her Majesty the Queen a very happy 90th birthday.

Queen Elizabeth II, who began her reign in 1952, has overseen 12 Prime Ministers and is Britain's longest serving monarch.

Today, numerous events will be held across the country to mark her 90th birthday, including a beacon lighting ceremony in Rickmansworth and Bedmond.

The Queen will light a symbolic beacon in Windsor. 

A photograph of the Queen with her two youngest grandchildren and five great-grandchildren has also been released.
