PRAGUE, May 17 (Reuters) - Support for the Czech left-wing Social Democrats has dipped ahead of elections on May 28029 but the party still holds a solid lead over its main right-wing rival and the strongest position for post-election talks on forming a cabinet, a poll showed on Monday.
Backing for the Social Democrats fell 0.8 percentage points from a month ago to 27.0 percent, but was still ahead of the right-wing Civic Democrats (ODS) who scored 18.7 percent, up slightly from 18.6 percent, according to the survey by STEM agency.
The poll showed that the Social Democrats together with the far-left Communists would win 103 seats in the 200-seat lower house, depriving the centre-right parties of any chance of forming a majority.
Such a result could lead to lengthy haggling over the next cabinet because the Social Democrats do not want to form a coalition with the Communists, still tainted by their totalitarian rule which ended in 1989.
The left-wing majority would however allow for a minority Social Democrat cabinet backed in parliament by the Communists, an acceptable option for the Social Democrats.
But they could first try to form a cabinet with some of the centre-right parties, the Social Democrats' preferred option, or possibly even a grand coalition with the Civic Democrats.
The STEM poll differed from recent surveys by other agencies which pointed to higher chances of a centre-right majority and showed the election outcome was still wide open.
The country has been led by a caretaker cabinet since a centre-right coalition collapsed last year, following an inconclusive 2006 election which gave both centre-right and left-wing parties 100 seats each in the lower house.
The country needs a workable cabinet to tackle the budget deficit and start long-neglected reforms of the pension and health care systems to avoid accumulation of fiscal imbalances in the future.

Pollsters: The CVVM, Median and Factum results are based on a model predicting gains at the ballot box, excluding those not willing to vote and undecided.
STEM results are direct voter preferences, and include replies from all respondents including those not willing to vote. Parties should thus win a larger than indicated share of the vote at the election. This is relevant mainly for small parties, which may cross the 5 percent threshold to win seats even if direct voter preferences show them below the minimum level.
