The 75-year-old monarch took a step back from his public duties after being diagnosed with an undisclosed form of cancer earlier this year. But a new report suggests he wants to return to the spotlight to attend his official birthday celebrations in London in June.
The Trooping of the Color is a ceremonial event held annually to celebrate the monarch's birthday. It's also known as the Sovereign's Birthday Parade and takes place in London with the monarch joining a procession of around 1,200 soldiers and musicians. It also involves a fly-past and an appearance by the monarch on the Buckingham Palace balcony.
