TPA troubles

So, the Charity Commission is investigating the Higher Rate Taxpayers Alliance after all. The key issue is really whether their research is political or educational. The TPA's chief exec said the following, which caught my eye:

"All the grants made by the Politics and Economics Research Trust have been for pieces of research which have been carried out with an open mind and to the highest possible academic level," he said.

I'd be interested to see if any of the TPA's research on pensions were funded by these grants, because I don't think they exhibit an openness to different policy options, and they contain factual flaws and misrepresentations. I would certainly struggle to class them as "the highest possible academic level".
