LONDON - The "Russia report" into Moscow's alleged meddling in British politics will be published today by the Intelligence and Security Committee after months of delays.

The Daily Telegraph has exclusively learnt that it will disclose Russia tried to "influence" the result of the Scottish independence referendum - but not the Brexit vote.

It will describe the Kremlin's attempt to divide the United Kingdom in 2014 as "the first post-Soviet interference in a Western democratic election". But the report concludes that there is no direct evidence of Russian influence in the 2016 Brexit referendum.

The findings of the 50-page report, which followed an 18-month parliamentary inquiry, will pile pressure on Prime Minister Boris Johnson to take a tougher line with Russian president Vladimir Putin. Last week, Foreign Secretary Dominic Raab said "Russian actors" tried to influence December's general election by circulating a leaked report on US-UK trade talks that was seized upon by Jeremy Corbyn.

The long-awaited Russia report is expected to be published this morning, nine months after its publication was blocked by Boris Johnson. The document is expected to explain the threat Moscow poses to the UK and what has been done to counter it.
