The Queen and other members of the royal family will attend a star-studded concert at London’s Royal Albert Hall on Saturday night, according to the official royal Twitter account.

The event, featuring performances from Sting, Shaggy and Kylie Minogue, will be broadcast live on BBC TV and radio.

The Queen welcomed Commonwealth leaders to Britain this week for a summit at which it was confirmed that her son, Prince Charles, would be the organization’s next leader.

On Sunday, she will start the London Marathon remotely from a special podium in the grounds of Windsor Castle. It will be 110 years after the 1908 Olympic Marathon was started at Windsor Castle by the then Princess Mary, grandmother to the Queen.

Next month, her grandson, Prince Harry, and Meghan Markle will wed at Windsor Castle.

The Queen also has an official birthday in June each year, celebrated with the traditional Trooping the Colour, a spectacular military parade.
