Support for Sweden's opposition far-right party has grown since its entry into parliament last year while all the members of the governing coalition have seen their ratings drop, a poll showed Monday.

The anti-immigration Sweden Democrats garnered 6.3 percent of voter support in Monday's poll by daily Dagens Nyheter and polling institute Synovate, up 1.7 percentage points from the last survey in December.

The party first entered parliament after a September election, obtaining 5.70 percent of the vote and 20 seats, after campaigning against the "dangers of Islamisation" and pledging to safeguard "traditional values".

Prime Minister Fredrik Reinfeldt's Moderate Party saw its support dwindle 1.7 percentage points from the last poll to 34.6 percent, while his coalition partners the Liberal and Centre parties, lost 0.8 and 1.1 percentage points, garnering 6.5 and 4.7 percent respectively.
