Italy’s interior minister and leader of League Party, Matteo Salvini, has called for a snap election, saying differences with coalition partners cannot be mended.
He said that a failed attempt by the Five Star Movement to derail plans for a high-speed rail link showed the coalition could no longer govern.
Five Star leader Luigi Di Maio said his party did not fear another election.
Matteo Salvini’s right-wing party is well ahead in opinion polls, due mainly to his stance against illegal immigration.
He is also very active on social media and has developed a “man of the people” image, pushing for tax cuts despite Italy’s €2.3tn debt mountain, which is second only to Greece’s in the EU.

In last year’s election, Five Star won twice as many votes as the League, but polls suggest the proportions have been reversed.
In EU elections held in May the League came top with 34% of the votes in Italy, whereas Five Star got about 17%.
Giuseppe Conte, the non-party law professor who serves as the coalition’s prime minister, has said Matteo Salvini, must “justify” to parliament his call for an election.
Both Matteo Salvini and Luigi Di Maio are deputy prime ministers.
The authority to dissolve parliament rests with President Sergio Mattarella, but he may be reluctant to do so, as next month lawmakers – who are currently on holiday – have to consider the 2020 budget.
Political clashes over the project for a railway between the Italian city of Turin and French city of Lyon led PM Giuseppe Conte to put tenders on hold in March.
The multi-billion-euro TAV (Treno Alta Velocità) link involves digging a 36-mile tunnel through the Alps.
The project is bitterly opposed by Five Star on environmental and cost grounds.
The League argues that the TAV project would create jobs and stimulate economic growth, and that moving freight from road to rail is environmentally friendly.
Supporters of the TAV project say it would halve the travel time between the two cities to just two hours. The tunnel would also make it possible to travel from Paris to Milan in around four hours, down from nearly seven.
The TAV project was launched 20 years ago and part of it has already been dug. It is scheduled for completion in 2025.
Costs were initially projected to hit €8.6 billion ($9.7 billion), but Italy’s Transport Minister Danilo Toninelli – a Five Star member – put the price tag at over €20 billion.
The EU pledged to fund up to 40% of the cost.
Matteo Salvini’s demand for an election does not necessarily mean a poll will be called in the near future. Italy has not had an autumn election in all the post-war period, Reuters news agency reports.
President Sergio Mattarella could theoretically appoint a government of technocrats and postpone a new election until next year.
Italy has had a technocratic government before, but Matteo Salvini, riding a wave of popularity, can be expected to oppose such a move.
