The 1929 UK general election was held on 30th May1929, and resulted in a hung parliament. Labour, led by Ramsay MacDonald, won the most seats (despite winning fewer votes than Stanley Baldwin's Conservatives), but did not hold an overall majority. The Liberals led by David Lloyd George regained some of the ground they had lost in the 1924 election, and held the balance of power.
Generally speaking, grassroots Labour voters are considerably to the left of Tony Blair and his followers in the political apparatus and government.
The ensuing generalelection saw the publication, four days before polling day, of the infamous Zinoviev Letter that implicated Labour in a plot for a Communist revolution in Britain, and the Conservatives were returned to power.
At the 1987 generalelection, the party was again defeated in a landslide, but had at least established itself as the clear challengers to the Conservatives, and had not been relegated to third place by the Liberal Democrat/SDP coalition, as some had feared.
