The public directly influences party policy, since, in order to be elected to govern,
parties must reflect the wishes and interests of the electorate in their programmes

If existing parties do not sufficiently represent sections of society, a new party will usually emerge.

Parties are accountable to the electorate, since they will not regain power if they disregard the opinions and interests of the public.

Parties cannot simply represent a sectional interest since, to be elected to power, they
require the support of various interests in society.

State’s most important function in a given society is maintaining order.
