Sir Elton John, the son of the late Princess Diana friend, and the country's popular music star, will sing in British Prince Harry's wedding. He was a close friend of Diana and they worked together for charitable organizations. She also sang at the funeral of Diana, who died in a tragic road accident in 1997.
Harry will be married to former Hollywood actress Megan Merkel on Saturday. Queen Elizabeth II has got official permission.
However, no political leader was invited to the royal wedding. It means that there is no possibility of British Prime Minister Theresa May being present at the royal wedding.
Harry is not directly the successor of British throne, so political leaders have not been invited.
