However, it is now understood Energy Secretary Ed Miliband has narrowed it down to three options - Glasgow, Edinburgh or Aberdeen. It means other areas which had been touted - such as Grangemouth, Greenock and Fife - will not be getting the GB Energy headquarters. On Thursday Energy Minister and Scottish Labour MP Michael Shanks officially introduced the GB Energy Bill in the House of Commons.

The new UK government also introduced a second Bill to give the Crown Estate borrowing powers to invest in wind farms. The Crown Estate owns large swathes of the sea bed around Britain. Mr Miliband said GB Energy would start making a profit within five years, and Sir Keir Starmer suggests it will bring down household energy bills by £300 a year.

So when it comes to making a decision on which city to choose, what are the pros and cons? Aberdeen Pros - Aberdeen has long been one of the favourites for the base, as it is the oil and gas.
