The president has cited opposition by some against the planned event as the reason for the cancellation.
Speakers at the workshop were to be Central Bank governor Dr. Indrajit Coomaraswamy on the economic crisis and international economic trends and MP Dr. Jayampathy Wickremaratne on constitutional amendments.
All SLFP MPs in the government excepting those presently accompanying prime minister Ranil Wickremesinghe in his foreign tour had agreed to take part.
However, minister Susil Premajayantha has told the president that it would be demeaning for the SLFP to obtain advice from an MP of the UNP.
The president has neither agreed to a suggestion by Kumaratunga to raise awareness on the MPs on economic affairs only.
