Francesco Gullino

Francesco Gullino (or Giullino) (born in Bra, Italy in 1946) is a Dane of Italian origin who was named in June 2005 by The Times as the prime suspect in the 1978 "Bulgarian umbrella" murder of Bulgarian dissident Georgi Markov. He was known by the code name "Piccadilly".

According to Bulgarian journalist Hristo Hristov, Gullino was an occasional smuggler arrested twice in Bulgaria and given the choice of going to prison or becoming a secret agent in the West. Based in Copenhagen with a cover as an art dealer, Gullino was supposedly active until 1990 and received two Bulgarian state medals “for services to security and public order”. He was briefly detained in 1993 and questioned by the British and Danish police in Copenhagen, and, according to Hristov, then dropped out of sight.

A British documentary, The Umbrella Assassin (2006), interviewed people connected with the case in Bulgaria, Britain and the United States, and revealed that Gullino is alive and well and still travels freely throughout the European Union.
