Four of the six candidates who did not make it to the second round, Matti Vanhanen, Bjarne Kallis, Henrik Lax and Arto Lahti publicly expressed their support for Sauli Niinistö in the runoff election. This reflects a loose alliance termed "porvariyhteistyö" in the Finnish media, (roughly translated as "bourgeois collaboration"). According to Niinistö and Vanhanen, the main centre-right parties (the National Coalition Party and the Centre Party) had agreed about a year earlier on some level of co-operation to better compete with Halonen, who was supported by both the Social Democrats and Left Alliance.
