What now for Witney?
Witney's MP is now Prime Minister - so what does that mean for people in West Oxfordshire?
Unlike in the United States, where the Head of Government (the President) has to give up representing a particular area upon being elected to the White House, in the UK, the Prime Minister continues to be a constituency MP.
This means David Cameron will keep on representing West Oxfordshire in Parliament, even though he will have a lot more work to do now.
Mr Cameron was re-elected by people in the Witney constituency in the General Election on Thursday 6 May 2010 with an increased majority of more than 22,000 votes.
In his acceptance speech he promised to continue doing his best for local people: "I will always work hard as a constituency MP, standing up for your interests, taking up your cases, acting on the things that you care about."
"It is an immense privilege and a pleasure to represent this wonderful part of our country. Eighty five rural parishes, wonderful market towns; a lovely part of our country but not without its issues and its difficulties and I will go on standing up for you and being a good constituency MP."
Because Witney is closer to London and Downing Street than Gordon Brown's constituency in Kirkcaldy, Scotland and Tony Blair's old seat at Sedgefield, County Durham, it's possible David Cameron may be able to get back to his constituency a bit more often than his two predecessors.
