How to use Aristotle

Ask Aristotle is the Guardian's politics database. It contains details of constituencies, MPs and parliamentary election candidates

A packed House of Commons

What can Ask Aristotle do?

Ask Aristotle knows about candidates for the 1992, 1997, 2001, 2005 and 2010 general elections. Anyone who stood in any constituency since 1992 is profiled, whether they won or lost, though you'll find more information about MPs than about candidates who were never elected.

Example: David Cameron's Ask Aristotle page

Ask Aristotle also has extensive information on each of the 646 constituencies in the United Kingdom.

Example: David Cameron's Witney constituency page

How do I find information?

Find your MP search box

The Find your MP search box appears in the right-hand column of virtually every article on the Guardian's website about UK politics (including this one).

Use the drop-down menu to find the constituency you're interested in or search by entering a postcode in the field headed Enter postcode.

Ask Aristotle understands both the opening part of a postcode - such as SW1A - and entire postcodes - such as SW1A 0AA and will show you a list of matching constituencies, or take you straight to the appropriate constituency page if there's an immediate like-for-like match.

The field headed Enter an MP's name returns a page powered by the Guardian's own search, which will contain a list of stories in our news archive that match your search request. The page will also show links to
tag pages, if such a page exists on our site for the person you're searching for.

How do I browse the Ask Aristotle database for people?

If you don't want to search for specific MPs or constituencies, you can view lists of MPs by party:

Labour MPs

Conservative MPs

Liberal Democrat MPs

Other parties

All MPs
