As expected, the talks with VVD (liberals, 31 seats), PvdA (Labour, 30 seats), D66 (Soc-Liberals, 10 seats), and GroenLinks (Greens, 10 seats) failed. Rutte (VVD) pulled th plug on this, because in his eyes his right wing party would be dominated by these three "left wing" parties. That's ofcourse a simplication, as D66 and to some extend, GroenLinks are quite progressive and pro-reform including economic topics were they favour various liberalisations/rule relaxing.
So a Paars (purple) cabinet with the above mentioned parties is out of the question for now...
Rutte has called for a meeting between VVD, CDA (ChristianDemocrats, 21 seats) and PvdA. Cohen (PvdA) has said he ain't keen on such a coalition. Though the three of them are going to engage in talks to form this "national" or "orange" cabinet.
Thus Rutte has closed the door to a centre-left cabinet, and Cohen the door to a centre-right cabinet.
Meanwhile, there is mentioning of inviting D66 and GroenLinks in these talks to form a "rainbow coalition" of the "rightwinged" VVD and CDA (31+21= 52 seats) and "leftwinged" PvdA, GroenLinks and D66 (30+10+10= 50 seats). On paper this should balance out to a centrist coalition. It would be rather large though, much larger then the 76+ minimum that is needed to gain a majority in the Tweede Kamer (Second Chamber, Lower house).
Wilders has asked to look at talks between his party (PVV, 24 seats) and CDA again.
