The new Dutch cabinet has a made a completely false start” when it comes being transparent about meeting lobby groups, the Open State Foundation said in a report on Monday.

The new administration took office two months ago, but since then ministers have failed to properly register which lobbyists they have met and what they talked about, the foundation said.

Ministers are supposed to register meetings in their public diaries to prevent any conflicts of interest taking place. So far, the 29 ministers and junior ministers in the right-wing government have registered 160 meetings with lobbyists, but only 13% of those have been reported in line with the guidelines.

Open State also found references to a further 33 on social media which had not been reported. The true total is likely to be higher because ministers do not publicise all their activities on social media, the anti-secrecy group said.

The coalition agreement between the four parties pledges to implement the Greco recommendations on ensuring ministerial integrity. The Group of States Against Corruption, part of the Council of Europe, has been highly critical of the lack of transparency over lobbying in the Netherlands.

At the time of the research, six ministers had not recorded any meetings at all and Judith Uitermark, whose portfolio includes transparent government, had only registered one.
