Notional 2005 Results: (estimates based on boundary changes)
Labour: 18105 (46.4%)
Conservative: 9341 (23.9%)
Liberal Democrat: 9261 (23.7%)
Other: 2307 (5.9%)
Majority: 8764 (22.5%)
So the new constituency is stronger for the Conservatives (who move into 2nd place), and for the the Lib Dems who would gain 3%. Labour lose out by the boundary change but, as stated on the site "the seat remains strong for Labour", 22.5% majority generally being regarded as a safe seat.
But as with all elections, it would be a shame to regard it as a completely forgone conclusion. It would be nice to think that there is some point in taking part in the democratic process, however 'safe' the seat may be.
