Gina Miller, the prominent City figure and campaigner, has called on the government to immediately release a report detailing Russian interference in UK politics and has revealed that she took legal action to try and get the dossier published.

Miller, who ran two successful legal campaigns against the UK government, told Financial News in an exclusive interview that she “tried and failed” to get Parliament’s Intelligence and Security Committee’s report released via “legal means”, adding that more pressure was needed to get the dossier published before the December 12 general election.
