MEPs examining the actions of the EU-IMF troika in programme countries like Ireland hope to have their draft report ready by Christmas.
The probe, which is being conducted by the parliament's economics committee, is already underway.
Questionnaires went out yesterday to the heads of government, the finance ministers, central banks of programme states, and to the troika.
EU sources told RTÉ News that the parliament's president Martin Schulz told rapporteurs this week that some heads of government are concerned that the examination could become a left wing vehicle for electioneering ahead of the parliamentary elections next May.
The parliament's committee was urged to keep the report factual.
It is understood a draft report should be ready to be considered by the Committee by 16 January.
An amended report for plenary should be ready by March.
