German conservative leader Friedrich Merz, the presumptive next chancellor, has won his constituency in Sunday's parliamentary election, while a number of political heavyweights suffered humiliating defeats.

German conservatives under Friedrich Merz vowed on Monday to quickly form a government after winning a national election but face tricky coalition talks and the prospect of an obstructive parliament after far-right and far-left parties surged.

Germany faces its second change of leader in less than four years after the head of the center-right opposition won Sunday’s election.

An election win for Germany's conservatives has eased concerns of political gridlock in Europe's biggest economy, though it failed to lift uncertainty around whether a new government can deliver fiscal reforms that would boost sluggish growth.

Germany's mainstream conservatives led by Friedrich Merz won the country's national election, ensuring that Ukraine has an even stronger supporter in the European Union's largest country and creating hopes for renewal in an economic powerhouse that has been badly battered in recent years.
