The due diligence document said Mandelson remained on the board of the Kremlin-linked defence company Sistema long after Putin's first invasion of Ukraine in 2014.

Russia's annexation of Crimea and incursion into Ukraine began in 2014. Reporting confirms Peter Mandelson joined the board of the Russian conglomerate Sistema and remained a director until 2017 - well after 2014. Sistema is a conglomerate whose subsidiary RTI supplies Russian defence/early-warning technology, so the 'defence company' framing is broadly accurate though Sistema is a diversified group.
