The Government is the group of people who Tony Blair has chosen to help him run the country.
There are normally about 100 people in a UK government.
This is different from Parliament. It is also different from the Labour Party.
The making of a Government
1 A general election is held. All 659 MPs are chosen when the country votes.
2 The votes are counted. The leader of the party with the most MPs can become Prime Minister.
3 The new Prime Minister choses a team of people from Parliament who will run the country with him.
4 Any MPs or Lords in the team he picks are now members of the UK Government.
