As it stands, it says:

Despite stereotypes of Oxford being a conservative city, there are no Conservatives on the city council. Since the local election in mid-2004, the council has been in minority administration by councillors from the Labour Party, with the Liberal Democrats being the official opposition. At 7 councillors, Oxford is one of the UK cities with highest Green Party representation on the council. The Independent Working Class Association also has councillors, mainly from wards with many housing estates in the southeast, such as Blackbird Leys.

The two MPs are Andrew Smith from the constituency Oxford East, erstwhile employment minister in the Labour government; and Evan Harris from the constituency Oxford West and Abingdon, sometime Liberal Democrat spokesperson on health. In the upcoming UK general election, 2005/06, the candidate for Oxford West and Abingdon are likely to be: Antonia Bance (Labour), Evan Harris (Liberal Democrats incumbent), Tom Lines (Green), and Amanda McLean (Conservative); for Oxford East: Steve Goddard (Liberal Democrats), Virginia Morris (Conservative), Jacob Sanders (Green), and Andrew Smith (Labour incumbent).
