The Deputy Prime Minister of the United Kingdom of Great Britain and Northern Ireland (DPM) is a senior member of the Cabinet of the United Kingdom. The office of the Deputy Prime Minister is not a permanent position, existing only at the discretion of the Prime Minister, who may appoint to other offices – such as First Secretary of State – to give seniority to a particular Cabinet Minister. The office was last held by Nick Clegg between 2010 and 2015, during David Cameron's first term as Prime Minister.
