Labour set to keep hold of Glasgow East?

According to a poll to be published in tomorrow's Sunday Telegraph Labour is set to hold Glasgow East with a fairly healthy majority:

Labour is on course to win this month’s crucial by-election in Glasgow East, according to an opinion poll.
The ICM survey for the Sunday Telegraph puts the party on 47 per cent of the vote with its nearest challenger, the Scottish National Party (SNP), on 33 per cent.

Liberal Democrats are on nine per cent and the Conservatives on seven per cent.

The poll, the first conducted within the rock-solid Labour seat, is a big boost for Gordon Brown.

Update UK Polling report has some interesting thoughts as to why this poll might not be quite the good news for Labour as the published figures might suggest
