LONDON (AP) — Thousands of police, hundreds of troops and an army of officials are making final preparations for the state funeral of Queen Elizabeth II. The funeral Monday will be a spectacular display of national mourning, and the biggest gathering of world leaders for years. U.S. President Joe Biden and other world leaders are arriving in London for the funeral. Thousands of people continued to line up Sunday to file past the queen’s coffin as it lies in state at Parliament’s Westminster Hall. The queen’s eight grandchildren led by Prince William circled the coffin in a silent vigil on Saturday evening.
