Stonehouse stood unsuccessfully in
Norwood at the
1949 London County Council election. He was first elected as the
Labour Co-operative Member of Parliament (MP) for
Wednesbury in
Staffordshire in a
1957 by-election, having contested
Twickenham in
1950 and
Burton in
1951. In February 1959, Stonehouse travelled to the
Federation of Rhodesia and Nyasaland on a fact-finding tour in which he condemned the
white minority government of
Southern Rhodesia (now Zimbabwe). Speaking to the
Southern Rhodesia African National Congress, he encouraged indigenous Rhodesians to stand up for their rights and said they had the support of the
British Labour Party. Stonehouse was promptly deported from Southern Rhodesia and banned from returning a year later. Stonehouse served as a junior minister of aviation, where he was involved in the
British Overseas Airways Corporation's order of
Boeing 707 aircraft from the United States, against his own recommendation that they should buy the Super
Vickers VC10, a British-made aircraft. This led to accusations by Stonehouse against colleagues about the reasons for the decision. In March 1968, Stonehouse negotiated an agreement providing a framework for the long-term development of technological co-operation between Britain and
Czechoslovakia providing for the exchange of specialists and information, facilities for study and research in technology, and such other forms of industrial co-operation which might be agreed. Stonehouse's rise continued while in the
Colonial Office, and in 1967 he became
Minister for Technology under Wilson. He later served as
Postmaster General, where his greatest contribution to the postal system was the introduction of first and second-class
postage in 1968, often called the two-tier post, which was met with a full day of debate on the floor of Parliament after a bungled marketing campaign. The debates over Stonehouse's leadership were followed shortly after by the abolition of the office of Postmaster General by the
Post Office Act 1969. As Minister of Posts and Telecommunications in 1970, Stonehouse oversaw the controversial
jamming of the
offshore radio station
Radio North Sea International. When Labour was defeated at the
1970 general election, he was not appointed to the
Shadow Cabinet. When the Wednesbury constituency was abolished in 1974, Stonehouse stood for and was elected to the nearby
Walsall North constituency in the
February general election. With Labour a
minority government, another election was called in September, and Stonehouse was re-elected with an increased majority of nearly 16,000 in the
October election, just six weeks before his disappearance. Stonehouse's last Parliamentary contribution before his disappearance was at
Prime Minister's Questions on 14 November 1974, a few days before leaving for
Miami, Florida. ==Spy allegations==
