Committee for State Security State Security played an active part in the so-called "Revival Process" to Bulgarianize the Bulgarian Turks in the 1980s, as well as writer and dissident Georgi Markov's 1978 murder on Waterloo Bridge in London known for the "Bulgarian umbrella" that was used. An issue the international community often raises is State Security's alleged control of the weapons, drugs, alcohol, cigarettes, gold, silver, and antiques traffic through Bulgaria before 1989. It is popularly thought that organised crime in the country in the 1990s was set up by former State Security agents. The agency is often incriminated with the ill-famed murder of
Waterloo Bridge as the South Bank, which includes the Royal Festival Hall, Waterloo station, Queen Elizabeth Hall and the Royal National Theatre, as well as the BFI Southbank, which is directly beneath the bridge. The north end of the bridge passes above the Victoria Embankment where the road joins the Strand and Aldwych alongside Somerset House. This end housed the southern portal of the Kingsway Tramway Subway until the late 1950s. The entire bridge was given Grade II* listed structure protection in 1981.
