For the British intelligence agency, it must have seemed like a good investment. Mussolini, then a 34-year-old journalist, was not just willing to ensure Italy continued to fight alongside the allies in the first world war by publishing propaganda in his paper. He was also willing to send in the boys to “persuade” peace protesters to stay at home.
Mussolini’s payments were authorised by Sir Samuel Hoare, an MP and MI5’s man in Rome, who ran a staff of 100 British intelligence officers in Italy at the time.
Cambridge historian Peter Martland, who discovered details of the deal struck with the future dictator, said: “Britain’s least reliable ally in the war at the time was Italy after revolutionary Russia’s pullout from the conflict. Mussolini was paid £100 a week from the autumn of 1917 for at least a year to keep up the pro-war campaigning – equivalent to about £6,000 a week today.”
