Files on the 1963 shooting of the US president in Dallas are due to be released next week, with President Trump having the final say on whether they are made public.

The assassination of Kennedy has been a rich source of conspiracy theories ever since gunman Lee Harvey Oswald fired three shots from the Texas School Book Depository at John Kennedy’s motorcade.

Long-secret files on the assassination are due to be released by the US National Archives next week, with Donald Trump having the final say on whether they are made public.

Ahead of the deadline, Trump revealed he would be allowing the documents to see the light of day, “subject to the receipt of further information”:

The magazine Politico earlier reported that the president would almost certainly block the release of some of the files, which include documents from the FBI and CIA.

White House spokesman Lindsay Walters told Politico the administration was working “to ensure that the maximum amount of data can be released to the public”.

The documents include more than 3,000 that have never been made public, and more than 30,000 that have been previously released.
