This article seeks to examine evidence that British political parties
may be in decline. A two-dimensional framework for analysis is utilize
d, which suggests that the overall picture is far from unambiguous. At
most, a prima facie case can be made that the popular legitimacy of p
arties may be dwindling; similarly, party organizations only appear we
aker than they were a generation ago at the local level - and even thi
s may be a somewhat simplistic account of the real strengths and weakn
esses of British parties given the emergence of the 'electoral-profess
ional' model. If we turn to a deeper level of analysis, we must conced
e that the capacity of parties to fulfil functions on behalf of the wi
der political system may not be what it once was in some respects; nev
ertheless, they remain central to the tasks of demand aggregation and
political recruitment. In short, political parties in the UK may have
their problems, but they remain much more than vestigial phenomena of
a bygone age. To a significant extent this is because of their undoubt
ed capacity to adapt to changing environments.
