Excerpt:
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.
