Could Brown go for a March 25th election?

The conventional wisdom in Westminster is that the election will be on May 6th. But a few shadow Cabinet members have told me that they think Brown will actually go in March, an idea that they have been pushing for a while. Their argument is that this quarter’s GDP figures will be quite good, boosted by the Christmas rush, and Brown would want to go to the country before, another more disappointing set of numbers came out.
