How green is Jo Swinson?

These donations, from Mark Petterson of Warwick Energy, the piece went on to point out, came after she had voted against an 18-month ban on fracking and against requiring frackers to get environmental permits.

Two and two, the article didn’t need to say, equals four – Swinson was in cahoots with the fracking industry.

And yet, how much scrutiny does this analysis bear? Petterson is a “lifelong supporter of the Liberals/SDP/Lib Dems” and, he tells ENDS, his company’s interest in oil and gas has always been a small part of its business.
