Commentators believed that an unexpectedly bad set of balance of payments figures (a £31-million trade deficit) published three days before the election and a loss of national prestige after the England football team's defeat by West Germany on 14 June in the
World Cup contributed to the
Labour defeat. campaigning in
York. Other factors that were cited as reasons for the Conservative victory included union indiscipline, rising prices, the risk of devaluation, the imposition of
Selective Employment Tax (SET), and a set of jobless figures released on final week of the campaign showing unemployment at its highest level since 1940. Interviewed by
Robin Day, the outgoing Prime Minister
Harold Wilson highlighted the possibility that "complacency engendered by the opinion polls" may have resulted in a poor turnout of Labour supporters. As
defending world champions, England's venture in the World Cup attracted a much keener public interest than the general election did. However an analysis by pollster
Matt Singh for the 50th anniversary of the election concluded that the late swing had been caused by the weak economic data and that there was "no evidence" that the World Cup had influenced the outcome. American pollster Douglas Schoen and
Oxford University academic
R. W. Johnson asserted that
Enoch Powell had attracted 2.5 million votes to the Conservatives, although the Conservative vote only increased by 1.7 million. Johnson later stated "It became clear that Powell had won the 1970 election for the Tories ... of all those who had switched their vote from one party to another, 50 per cent were working class Powellites". The Professor of Political Science
Randall Hansen assessed a range of studies, including some which contended that Powell had made little or no difference to the result, but concluded that "At the very least, Powell's effect was likely to have fired up the Conservative vote in constituencies which would have voted Tory in any event". Election night commentators
Michael Barratt and Jeffrey Preece dismissed any special "Powell factor", as did Conservative MPs
Reginald Maudling,
Timothy Raison and
Hugh Dykes. Unusually for the
Liberal Party, the by-elections between 1966 and 1970 had proved almost fruitless, with many Liberal candidates losing deposits. The one exception was its
by-election gain of Birmingham Ladywood in June 1969; this was promptly lost in the 1970 general election. The party found itself struggling to introduce its new leader
Jeremy Thorpe to the public, owing to the extensive coverage and attention paid to
Enoch Powell. The election result was poor for the Liberals, with Thorpe only narrowly winning his own seat in
North Devon. The BBC's election coverage was led by
Cliff Michelmore, along with
Robin Day,
David Butler and
Robert McKenzie. The BBC coverage was parodied by ''
Monty Python's Flying Circus'' in its famous "
Election Night Special" sketch. Both BBC and
ITN carried their 1970 election night broadcasts in colour, although segments broadcast from some remote locations and some BBC and ITN regional bureaus were transmitted in black-and-white. Some
ITV regions were not yet broadcasting in colour at the time of the 1970 elections. The
right to vote in this election was widened by the Labour government's
Sixth Reform Act, which reduced the
voting age from 21 to 18 years. The United Kingdom was the first major democratic nation to extend suffrage to this age group. Case law subsequently established the right for
undergraduate students to vote in the constituency of their university. This followed an appeal to the
High Court. ==Timeline==
