Labour criticises tender as firm running £400m investment fund awards millions to company it part-owns The private equity firm appointed by the government to manage as much as £400m in investment in electric car charging points has awarded millions of pounds to a company in which it holds a controlling financial interest. Zouk Capital is the largest shareholder in charge point builder Instavolt, having made an £18m investment in the company. Now Zouk has chosen Instavolt as the charge point fund’s first beneficiary, a decision criticised by the Labour party.
