Minority government is rare in the UK, but relatively common in many other parliamentary democracies. In this post Jonathan Boston considers the prospects for Theresa May’s government. He draws on the experience in New Zealand, where since becoming the norm in the late 1990s minority governments have proved durable. However, he argues that present circumstances in the UK mean that May’s current government is very unlikely to last a full term.
Minority governments in Britain are relatively rare. But this is not the case in many other parliamentary democracies, especially those with proportional representation voting systems.
During the post-war period, about a third of governments in advanced democracies lacked a parliamentary majority. They were thus dependent on one or more supporting parties, often through a negotiated agreement on matters of confidence and supply. Such agreements vary significantly in policy specificity, consultative arrangements and expected duration.
Minority government in New Zealand can be effective and durable
In New Zealand, there were no post-war minority governments until 1996 when the mixed member proportional (MMP) electoral system was introduced. The impact was immediate and significant: no party has won an overall parliamentary majority since then and during most of these years the party or parties represented in the cabinet lacked a majority.
It has, however, developed some novel governance arrangements to cope with the political exigencies of MMP. In most parliamentary democracies, members of parties supporting a minority government do not hold ministerial office. In New Zealand, by contrast, it is common for only one party to be represented in the cabinet; this party, in turn, is supported by several minor parties, each of which holds a ministerial post outside the cabinet.
Collectively, the government and support parties have a parliamentary majority, but ministers outside the cabinet are not bound by collective cabinet responsibility unless specifically agreed between the parties. There is, in effect, ‘selective collective responsibility’, with ministers able to advance different views publicly on important matters of public policy.
These arrangements have proved both effective and durable: the 1999 Labour-led Government survived three terms in office and the current National-led Government, formed in 2008, is close to completing its third term and will likely retain office after the election in September.
