The Queen has attended the final night of an equestrian extravaganza show to celebrate her Platinum Jubilee.

The 96-year-old was met with a standing ovation as she arrived in the castle arena at the Royal Windsor Horse Show.

Celebrities including Tom Cruise, Helen Mirren, and Katherine Jenkins appeared at the open-air celebration.

It has been running since Thursday night and is the beginning of celebrations to mark the Queen's 70-year-reign.

Crowds of people cheered as the smiling Queen arrived for the final night of the show marking her 70-year-reign

The crowd cheered as the smiling Queen arrived and made her way to the royal box, accompanied by the Earl and Countess of Wessex.

She has mobility problems and has had to cancel a number of recent public appearances.

The Queen was spotted on Friday at the horse show, where one of her own horses was announced as a supreme champion.

On Tuesday, she missed the annual reading of the Queen's Speech for the first time since 1963.

The show, called A Gallop Through History, featured more than 500 horses and 1,000 performers.

Billed as a "personal tribute to our monarchy", the production takes the audience through more than five centuries of history.

It features international and national military, equestrian and dance displays.

Tom Cruise announced the performance of the King's Troop Royal Horse Artillery as "one of the most enthralling, thrilling, heart-in-mouth displays".

The Trinidad and Tobago Defence Force's steel drum troupe performed a rhythmic version of Abba's Dancing Queen - which the Queen appeared to enjoy.

She was also seen clapping during a traditional display from the Royal Cavalry Oman, a show of horsemanship that saw horses lying down on command.
