One in three (9 out of 26) outgoing commissioners who left office in 2014 have gone through the 'revolving door' into roles in corporations or other organisations with links to big business, leading to fears of an unhealthily close relationship between the EU's executive body and private interests. In our view, at least eight revolving door roles, held by four commissioners, should not have received authorisation at all, due to the risk of possible conflicts of interest.
