After completing his first degree, Mbeki planned to join uMkhonto we Sizwe (MK) and he sought permission to do so, but this plan was vetoed by Tambo, who advised him to do a Master's degree. In October 1965, Mbeki returned to Sussex for one year to do his Masters in Economics and Development. Mbeki at this time shared a flat with Peter Lawrence and Ingram, situated at 3 Sillwood Street. While in England, Mbeki supported the Labour Party, then-led by Harold Wilson. Mbeki was intensely critical of the New Left revision of Marxism that swept Europe in the latter half of the 1960s and remained ardently loyal to the Soviet Union, which at the time heavily sponsored the ANC's underground movement, providing them with financial and educational support, as well as arms and military training. On 18 May 1966, Mbeki organised a 24-hour vigil at the Clock Tower in Brighton's central square against Ian Smith's Unilateral Declaration of Independence in Rhodesia. In October 1966 Mbeki moved to London to work for the ANC full-time. During this period he met his wife to be, Zanele Dlamini, a social worker from Alexandra Township in Johannesburg, who was also studying in London. Zanele had just moved to London at this time.
