LONDON — The scale is epic: potentially millions of people thronging the streets, more than 100 foreign dignitaries and their staffs streaming in from around the world, hundreds of domestic and international government agencies coordinating logistics, large swaths of roads and transportation networks closed or gridlocked.
For London's Metropolitan Police — the storied force also known as Scotland Yard — the funeral of Queen Elizabeth II on Monday promises to be a security challenge unlike any it has faced.
"It's probably the largest public-order type or ceremonial event the U.K. has ever held," said former police Chief Supt. Parm Sandhu. "Even when the Queen Mother died or [Princess] Diana, it wasn't as large as this."
