The facts: nineteen contracts out of thirty-one, €9.4 M; three bidders at the same address and under the same holding; nine votes without recusal; €310,000 in grants to the family’s association; €900,000 in public aid paid on a site barely opened.
Grey areas: whether competition was real on the twelve single-bid contracts; the association’s accounts for the three unpublished years; how the land price was set.
What to watch: next council meeting, next declaration of interests, next published accounts.
