From memory -
Blair used a Sikorsky S-76 and (I think) a Eurocopter Super Puma during the last Election.
He used a Super Puma in the February preceding the Election for the launch of the Labour party's pledge card - whatever that was.
PS:
You are, of course, free to write as you wish. However, it does seem a little odd that a professional wordsmith doesn't use capitals where appropriate.
Do you write for the Grauniad?
