Interest groups are associations of individuals or
organisations that on the basis of one or more shared
concerns, attempts to influence public policy in its
favour usually by lobbying members of the government.
Interest groups influence on policy making is not a
corrupt or illegitimate activity per se, but a key element
of the decision-making process. However,
disproportionate and opaque interest group influence
may lead to administrative corruption, undue influence,
and state capture, favouring particular interest groups
at the expense of public interest
