A good poll to kick off the short campaign

ICM -

Con 37% (down 1)
Lab 33% (up 4)
LD 21% (down 2)

a) ICM are seen by other pollsters as the "gold standard" for accuracy
b) this percentage share would make Labour the largest party in the Commons by about a 25 seat margin
c) traditionally there's about a 5% swing back to the government during most UK General Election campaigns - it only need a 2% swing for Labour to be level with the Tories and back on the score we got in 2005
