STOCKHOLM (Reuters) - Swedes would deliver another hung parliament if an election were held today, a poll showed on Tuesday, heaping pressure on mainstream parties to break the deadlock that has left the country without a government since September's vote.
The four-party, centre-right Alliance was supported by 37.5 percent down from 40.3 percent in the Sept.9 election, a twice yearly poll by the statistics office showed on Tuesday.
The centre-left bloc of the Social Democrats, Greens and Left Party, got 42.9 percent against 40.7 in September.
The anti-immigration Sweden Democrats, who hold the balance of power in parliament, saw their support rise to 18.3 percent from 17.5 percent.
