Kim Philby could have been unmasked as a Soviet double agent more than a decade before his eventual defection had MI5 not missed an opportunity to question his close friend Flora Solomon, according to newly released intelligence files.
Solomon, born in Russia to a wealthy family, was a former lover of Alexander Kerensky, the Russian leader deposed by Lenin. She told MI5 in 1962 that Philby had tried to recruit her as a Soviet spy in 1937-38.
