Alleging a conspiracy after electoral defeat, a politician with this first name described himself as “the big fat spider in the corner” to the journalist duo Pencourt. Peter Wright detailed MI5 plots against a leader with this first name in Spycatcher; that leader himself rose to power after the suspicious death of Hugh Gaitskell. A leader with this first name promoted a policy of no independence before majority rule, which prompted (*) Rhodesian independence, while another discussed (10[1])a “growth of national consciousness” in a speech in Cape Town. A leader with this first name was Prime Minister during Enoch Powell’s “Rivers of Blood” speech, and was surprisingly defeated in 1970 by Edward Heath. For 10 points, give this first name of British Prime Ministers MacMillan and Wilson. ■END■
