The three-party coalition is doomed to fall apart as the ruling parties' leaders failed to find a common ground on Monday and politicians were prepared for talks to form a new government.

The Suomen Keskusta( Centre Party) Prime Minister Juha Sipilä said on Monday afternoon that cooperation with the Perussuomalaiset (Finns Party) as a coalition partner ended, as the "ideological distance" had become too wide following the election of hardliner Jussi Halla-aho as the party chairman.

Sipilä noted that the other coalition parties had made many compromises with the True Finns and vise versa, but the situation looked too difficult for all the parties to go ahead.

The Prime Minister said Monday night on national TV that he would probably go to see President Sauli Niinistö on Tuesday afternoon to submit the formal resignation.

Sipilä and the the Kansallinen Kokoomus (National Coalition Party) leader Petteri Orpo conducted talks with Halla-aho on Monday morning, and the ideological gap was too wide to create the trust regarding decisions in future situations.

Veteran political analyst Unto Hamalainen, interviewed on Yle, formulated the situation as "the True Finns did not pass the risk analysis of the prime minister".

Halla-aho said later in social media that a key question was that Sipila was not willing to tighten the immigration policies.

RADICALS REMOVED

The True Finns underlined that they did not want to leave the government. Party vice chairman Laura Huhtasaari said on TV on Monday night the party had not resigned from the cabinet.

Analyst Hamalainen, saw no alternatives left for the coalition except taking on board the Swedish People's Party and the Christian Democrats. He believed a new government could be formed before the Midsummer holiday in late June.

The decision to take in the Swedish party and the Christian democrats would give the new government 101 seats out of 200-member parliament.

There was also widespread speculation Monday night in Helsinki that some MPs of the current True Finns caucus would defect to other parties and offer support to a new government.

Sipilä has admitted the government program will have to be negotiated, at least partially. Both the Swedish party and the Christian Democrats have already indicated they set some policy conditions for their possible entry.

END OF NEUTRALIZATION

Known for his anti-EU and anti-immigration stance, Halla-aho was elected chairman to succeed moderate Timo Soini in the Finns Party convention on Saturday.

The takeover of the radical right in the convention on Saturday and its repercussions on the coalition government on Monday marked an almost historic change in the way the political parties relate to each other in Finland.

It ended at least for the time being the Finnish tradition of "melting down" protest movements through incorporating them into the government. It had been believed that giving responsibilities would help neutralize the radicals.

In a commentary on Monday, the newspaper Keskisuomalainen warned that the decision not to cooperate with the True Finns may lead to further radicalization in the party.

It could also strengthen support for extremism, Keskisuomalainen wrote.
