AMSTERDAM (Reuters) -Dutch far-right leader Geert Wilders toppled the ruling coalition on Tuesday, gambling that a snap election focused on immigration will bring victory at the polls and secure his decades-old ambition of holding the highest political office.

The decision means the Netherlands will have a caretaker government when it hosts a summit of NATO leaders in three weeks. No date for a new election has been set, but it is unlikely before the fall.

Prime Minister Dick Schoof stepped down, setting the stage for a snap election.
