STOCKHOLM (Reuters) - Sweden's ruling centre-left bloc commanded a marginal lead over the centre-right Alliance in Sunday's national election with the unaligned, anti-immigration Sweden Democrats making gains, preliminary election authority results showed on Sunday.
The results after 4,800 of 6,004 districts had been counted, showed the governing Social Democrat and Green party coalition, together with the Left Party, winning 40.6 percent of votes, the election authority data showed.
The Alliance opposition bloc, composed of the Moderates, the Christian Democrats, the Centre party and the Liberals, looked set to win 40.1 percent.
The nationalist Sweden Democrats were on track to get 17.8 seats.
The results are partial and may differ slightly from the final outcome.
