It might be a whole year away, but organisers are already planning a four-day extravaganza to celebrate the Queen turning 90, it has been revealed.

Singer Katherine Jenkins will be among those performing at the event next May - which as well as a milestone birthday will make Elizabeth II the longest reigning British monarch.

The theatrical spectacular will also feature 550 horses and 1,200 participants including musicians, dancers, choirs and famous actors, actresses and artists.

Members of the royal family will attend the show each night and the Queen will go to the last performance on May 15, which will be broadcast live on TV.

The participants will reflect The Queen's private and public interests and performers will come from a number of countries including Oman, Chile, New Zealand, Canada, Fiji and South Africa.

It will also include members of the military, The Queen's Mounted Troops and over 100 pipers.

Any proceeds from the event will be donated to a number of the Queen's Charities.

Event director Simon Brooks-Ward said: "There will be a very happy and celebratory feel to the whole event.

"We have been delighted with the level of response from funders and participants. It should be a very special and memorable occasion."
