A four-day celebration will take place at Windsor Castle this week to mark Queen Elizabeth II's 90th birthday, with performances from Kylie Minogue, Katherine Jenkins and Jess Glynne. Although the Queen's actual birthday took place in April, official festivities to celebrate Britain's longest-reigning monarch will not take place until June.

This week's event will tell the story of the Queen's life and reign, including her involvement with the armed forces and her passion for horses. Over 90 minutes, more than 1,500 participants including actors and dancers will tell her story from her birth through to her involvement in the Second World War, her marriage, her coronation and her long reign.

Performers will come from a number of countries including Canada, Fiji, Chile, New Zealand, Australia, Azerbaijan, Oman and Britain. The Queen's Mounted Troops and more than 100 pipers will also be in attendance. The celebrations will take place in a purpose-built arena with a 25,000 capacity.

When will it take place?

The Queen's 90th birthday celebration event will take place over four nights from 12 to 15 May in Home Park Private, Windsor Castle. It is a non-profit event to raise money for charities.

Who will be there?

Members of the royal family will attend the event each night, including the Queen and her husband the Duke of Edinburgh who will be there for the finale. Kylie Minogue, Katherine Jenkins and Jess Glynne are set to perform on the final night of the celebrations, with Dame Shirley Bassey and Gary Barlow also set to perform for the Queen.

Academy Award-winning actress Dame Helen Mirren, Star Wars actor John Boyega, singer Alfie Boe and actor Damian Lewis will also be making an appearance. The show will be hosted by Ant and Dec.

Where can I watch it?

Tickets to the events sold out last November, but ITV will air the final night of the celebration from 8.35pm on Sunday 15 May.
