It was known that there was considerable resistance to this collaboration, especially within GroenLinks – the largest party in the Utrecht city council. Alderman Lot van Hooijdonk previously announced that she would quit, officially because her ‘pipe was no longer full enough’. The timing of her departure, just after the announcement of the collaboration, was striking, according to political followers. Van Hooijdonk has made no secret of his opposition to the merger of the factions.
