Con only really need 315 seats - not 325

[WetAugust]

650 MP but Siin Fein don't take up their seats so don't vote.

Say SF get 5 again this time:

650 - 5 = 645

Half of this for overall majority = 323

Tories can count on 8 DUP (if they got same as 2005) so

323 - 8 = 315 Conservative seats needed to win

Thank you for this, been waiting in vain for someone on the BBC to explain....

Agree Minthumbug that GB has first dibs if it's a hung parl but if the Cons reach a formal agreement with the DUP then they could vote GB down at evry count forcing him out of office
