A BBC programme "The Plot Against Harold Wilson", broadcast in 2006, reported that, in tapes recorded soon after his resignation, Wilson stated that for eight months of his premiership he didn't "feel he knew what was going on, fully, in security". Wilson alleged two plots, in the late 1960s and mid-1970s respectively. He said that plans had been hatched to install Louis Mountbatten as interim prime minister. He also claimed that ex-military leaders had been building up private armies in anticipation of "wholesale domestic liquidation". On a separate track, elements within MI5 had also, the BBC programme reported, spread black propaganda that Wilson and Marcia Williams (Wilson's private secretary) were Soviet agents, and that Wilson was an IRA sympathiser, apparently with the intention of helping the Conservatives win the February 1974 election.
