Investigation into foreign funding and support of jihadi groups operating in UK understood to focus on Saudi Arabia.
An investigation into the foreign funding and support of jihadi groups that was authorised by David Cameron may never be published, the Home Office has admitted.
The inquiry into revenue streams for extremist groups operating in the UK was commissioned by the former prime minister and is thought to focus on Saudi Arabia, which has repeatedly been highlighted by European leaders as a funding source for Islamist jihadis.
The investigation was launched as part of a deal with the Liberal Democrats in exchange for the party supporting the extension of British airstrikes against Islamic State into Syria in December 2015.
Tom Brake, the Lib Dem foreign affairs spokesman, has written to the prime minister asking her to confirm that the investigation will not be shelved.
The Observer reported in January last year that the Home Office’s extremism analysis unit had been directed by Downing Street to investigate overseas funding of extremist groups in the UK, with findings to be shown to Theresa May, then home secretary, and Cameron.
However, 18 months later, the Home Office confirmed the report had not yet been completed and said it would not necessarily be published, calling the contents “very sensitive”.
A decision would be taken “after the election by the next government” about the future of the investigation, a Home Office spokesman said.
