It would appear that many, very many Labour candidates see Tony Blair as a liability. They have been given the choice of two different leaflets, only one of which includes a message from Tony Blair along with his photograph. The full article is subscription only, but some key quotes below:

Mr Blair has been seen as a major electoral asset since becoming Labour leader in 1994 - and his picture featured on most leaflets at the 1997 and 2001 elections. However, soundings among Labour MPs suggest a majority of them will choose not to have Mr Blair on their leaflets, after voters lost trust in him over Iraq.

One MP said: "I don't think the party will find many takers. Many of us are opting for the other leaflet. I'll be using a picture of a red rose but not him. Even the most loyal MP knows he is a liability."

If most Labour MPs know that Blair is a liability, then why did they choose to stick with him as leader in spite of the opportunities they have had to unseat him. So when (or possibly if) you get a leaflet pushed through your letter box exhorting you to Vote Labour, then check for the mention of Tony Blair. If you find none, then ask someone from your Constituency Labour Party why Blair is missing from the leaflet and why, if Blair is such a liability, Labour did nothing about him.
