Question to the Ministry of Defence:
To ask the Secretary of State for Defence, on how many occasions footage of test firings of Trident missiles has (a) been made available to the media and (b) not released to the media following each such test firing in each year for which records are available.
This is decided on a case by case basis dependent on security considerations at the time. Footage of the 2005 and 2012 Demonstration and Shakedown Operations firings was released.
