http://www.financialcalculus.co.uk/election/This will be in multiple parts. I'll try and call all 650 or so seats.
First up- North London
(Incumbent in brackets, if open then none)
Barking (Margaret Hodge): She's Children's Minister and Barking is solidly Labour. LAB Hold.
Bethnal Green and Bow (Oona King): Galloway's turning up in this ethnic minority constituency means that this pro-war MP will be in for one rough ride. Expect this to be very nasty. I don't think Galloway can do it, but I could be wrong. LAB Hold.
Brent East (Sarah Teather): The by-election was probably a protest vote and this may well go back. LAB gain from LD.
Brent North (Barry Gardiner): He's a minister now. LAB Hold.
Brent South (Paul Boetang): He's an ethnic minority candidate in an ethnic minority borough. Plus he's in the Cabinet. LAB Hold
Chingford and Woodford Green (Iain Duncan Smith): He may have been sacked by his party, but he won't be by the electors. CON Hold.
Chipping Barnet (Sydney Chapman): Don't know enough for this. CON Hold.
Cities of London and Westminster (Mark Field): It's a business vote. CON Hold
Dagenham (Jon Cruddas): White, East End. He may be furniture, but this went Labour in 1983. LAB Hold
East Ham (Stephen Timms): See above. LAB Hold
Edmonton (Andy Love): LAB Hold
Enfield North (Joan Ryan): LAB Hold
Enfield Southgate (Stephen Twigg): This was
the election night surprise in 1997 when Portillo was unseated. The Tories have very little chance of taking it back. LAB Hold
Finchley and Golders Green (Rudi Vis): On different boundaries this was Thatcher's old seat. If the Tories have a decent night, they could pick it up. On current projections, they won't. LAB Hold
Hackney North and Stoke Newington (Diane Abbott): Private school, schmivate school. LAB Hold.
Hackney South and Shoreditch (Brian Sedgemore): LAB Hold
Hammersmith and Fulham (Iain Coleman) LAB CON Gain
Hampstead and Highgate (Glenda Jackson): LAB Hold
Harrow East (Tony McNulty): LAB Hold
Harrow West (Gareth Thomas): LAB Hold
Hendon (Andrew Dismore): LAB Hold
Holborn and St Pancras (Frank Dobson) LAB Hold
Hornchurch (John Cryer): A marginal, which could go either way. Small swing needed, but popular rebellious MP. NO CALL.
Hornsey and Wood Green: (Barbara Roche) LAB Hold
Ilford North (Linda Perham): CON Gain from LAB: Perham's in trouble. She needs a small swing to unseat her and it will probably happen.
Ilford South (Mike Gapes): LAB Hold
Islington North (Jeremy Corbyn): LAB Hold
Islington South and Finsbury: The Liberals second placed but they won't win this time. LAB Hold.
Kensington and Chelsea: Portillo's gone, but this seat is staying Tory. CON Hold
Leyton and Wanstead (Harry Cohen): LAB Hold.
Poplar and Canning Town (Jim Fitzpatrick): No Galloway, no problem. He'll walk this. LAB Hold.
Regent's Park and Kensington North (Karen Buck): LAB Hold.
Romford (Andrew Rosindell): New dog, new term. Surprisingly this was Labour under different boundaries from 1955-1970. CON HOLD
Tottenham (David Lammy): LAB HOLD
Upminster (Angela Watkinson): This was one of the few Tory pickups in 2001. Last election on these boundaries, then it ends up safe Tory. CON HOLD
Walthamstow (Neil Gerrard) LAB HOLD
West Ham: Banks is retiring (and insulted his constituents into the bargain), but his successor will have a clear run. LAB Hold
