Billionaire Andrej Babis's ANO party cruised to victory in the Czech Republic's parliamentary election, raising the prospect of a government that would boost Europe's populist, anti-immigration camp and reduce support for Ukraine.

An ebullient Babis told supporters that ANO would seek a one-party cabinet but would talk with two small parties - including the far-right SPD - for support as his party will lack an outright majority.

He again rejected accusations that his win would make the central European nation a less reliable European Union and NATO partner.

With nearly all results in, ANO was set to replace the current centre-right cabinet led by Prime Minister Petr Fiala.
