The absence of a codified constitution means prime ministers can act their role as they feel suits them.
It has been argued that UK prime ministers are starting to increasingly resemble presidents, examples of this would be Wilson, Thatcher and Blair as they emphasise the dominance of the prime minister over cabinet.
By becoming more presidential, the roles and influence of prime ministers have changed the working of UK government in the following ways:
There has been a growth of ‘spatial leadership’, which is when a prime minister distances themselves from their parties or government by presenting themselves through the use of a personal ideological stance, both Thatcher and Blair did this in their governments and have brought new ideologies by the names of Thatcherism and Blairism to politics.
’Populist outreach’ has become a tendency for prime ministers to attempt to relate with the members of the public by revealing their deepest hopes and fears for the country as reflected by prime ministers speaking for the nation over major events, crises or major news stories, this is where the media concentrates more on the prime minister as a personal spokesman for the government as a whole.
