Queen Elizabeth II became the first British Monarch to celebrate a Platinum Jubilee earlier this year after marking 70 years of service to the people of the United Kingdom, Realms and the Commonwealth. In honor of the milestone anniversary, thousands of street parties are scheduled to coincide with days of royal celebrations honor the queen’s historic reign, including two bank holidays planned on Thursday and Friday for a four-day, holiday weekend. Buckingham Palace shared that the queen’s attendance at events throughout the Platinum Jubilee weekend will likely only be confirmed on "the day itself," and Prince William and wife Kate Middleton were tapped to lead the Jubilee celebrations as the most senior members of the royal family. The Royal Family’s official social media accounts have teased access to Jubilee preparations, and will share behind-the-scenes looks at what’s to come for the big weekend in royal history. Queen Elizabeth II will begin Platinum Jubilee celebrations on Thursday with Trooping the Colour.
