Sweden's ruling centre-right coalition saw its approval rating jump in a poll published Friday, although the opposition still appeared best positioned to win the September 19 elections.

• Tax hike plans sink Swedish left-wingers
• Sweden government pushes fiscal responsibility

The Novus poll, published in the financial daily Dagens Industri, showed that 44 percent of the 1,000 people questioned from May 6-11 believed the left-leaning opposition would win the election, compared to 37 percent for the current government.

A string of other surveys in recent months have also credited the opposition with a clear majority of voter intentions.

But amid heightened economic angst in Europe linked to the Greek debt crisis, Sweden's ruling coalition, which has widely been hailed for safely ushering the non-eurozone country through the global financial crisis, has seen a clear hike in approval.

The Novus poll shows the opposition's lead is narrowing: In a February poll by the same institute, 55 percent said they expected the opposition to win the September vote while only 30 percent thought Prime Minister Fredrik Reinfeldt would remain at the helm for another four years.

And amid increased focus across the European Union on the importance of good public finances, Swedes, according to Friday's poll, have far more confidence in the centre-right government when it comes to economic policies.

The poll showed 45-percent-support for the government's economic policy, compared to just 34 percent for economic proposals from the Social Democratic, Green and Left parties aiming to form a new coalition government in September.

The poll also handed Reinfeldt's government a clear lead when it came to job creation (41 versus 39 percent), taxes (46 versus 36 percent) and business policies (56 versus 22 percent).

The opposition coalition, led by Social Democrat Mona Sahlin, was meanwhile credited with the best policies on healthcare (49 versus 30 percent) and on environment and climate issues (58 versus 21 percent).
