When in government; policy-making role of the Party is the same as policy-making by the Government; most policy is made by Minister and their civil servants and advisers; backbenchers get some say through conferences and committees but not much.
When in opposition; general membership of the party dictates policy direction through conferences and party committees, and the opposition leadership reflects this; sometimes this is not the case, eg Starmer's opposition to Momentum.
Representation Function of Political Parties
Seek to ensure all members of society have their voices considered and reflected in government decisionmaking.
Emergence of populist parties can change this function.
Rise of 'issue parties' = Green Party; represent a specific cause.
Selecting candidates
Need to find prospective candidates for local councillors, elected mayors, MPs.
Done at a local and regional level through party committees staffed by activists.
National Party leadership may have some say in which candidates are chosen.
All-Women shortlists introduced.
Identifying leaders
Positive identification; In 2016, Theresa May was overwhelmingly favoured by Conservative MPs and members so all opponents withdrew from leadership contest - made the Party appear united.
Negative identification; In 2015, the Party membership elected Corbyn but were at odds with the more moderate Labour MPs and Peers - made Party appear weak.
Political Education
Constantly educate people about political issues, explaining their ideas on how to approach key issues.
Educate the Public about how the electoral system works - major parties educated voters about new Voter ID laws.
Arguably this function has declined; media has now taken over role in informing the public and educating them.
