Theresa May is failing to keep Britain secure, Liberal Democrat leader Tim Farron has claimed, as he called on the Prime Minister to publish a report thought to focus on alleged Saudi funding of extremist groups in the UK.
Mr Farron said that the Prime Minister must be ready to have "difficult" talks with the Gulf kingdom, to which the UK recently approved arms export licences worth £3.5 billion.
In the wake of Saturday's terror attack at London Bridge, Mr Farron accused Mrs May of making the wrong choices on security, reducing police funding while handing billions to business in corporation tax cuts.
And he dismissed the Prime Minister's call for tighter regulation of the internet as "posturing", arguing that she should instead be working with online giants to develop methods for keeping people safe while maintaining free speech.
Mrs May's predecessor David Cameron agreed to an inquiry into foreign funding of Islamist extremists in 2015 as part of a deal with the Lib Dems in return for their support on the extension of air strikes into Syria.
Reports last week suggested that the findings may never be published because of the sensitivity of information about Saudi Arabia, though the Home Office said a decision on its release would be made after the election.
