By Andreas Rinke and Matthias Williams BERLIN (Reuters) -Election winner Friedrich Merz on Tuesday ruled out a quick reform to Germany's state borrowing limits known as the "debt brake" and said it was too soon to say whether the outgoing parliament could wave through a massive military spending boost.

Germany's outgoing parliament could still greenlight a new special fund to boost defence spending but reforming strict limits on state borrowing will be deferred to the new one, a senior ally of election winner Friedrich Merz said on Tuesday.

With German politicians now debating potential abrupt reforms to the country's strict balanced budget rules, some left-leaning politicians found themselves exasperated by conservative leader Friedrich Merz's quick post-election reversal on the issue.

Germany's likely next Chancellor Friedrich Merz questioned on Sunday whether NATO would remain in its "current form" by June in light of the comments by U.S. President Donald Trump's administration, and that Europe must quickly establish an independent defence capability.

Election winner likens the Trump administration to Putin’s Russia as he bids to take Europe in a new direction.

Germany's mainstream conservatives have won the country's national election, while a far-right party surged to become the country's second-largest party.
