National Dialogue Forum Chairperson Muyunda Mwanalushi says the 37 UPND Members of Parliament that have stayed away from the National Dialogue Forum risk being prosecuted.
Professor Mwanalushi said the MPs have committed an offence and the law will take its course.
He said in line with Article 17 of the NDF Act, the MPs may be fined penalty units not exceeding 50,000 or imprisonment not exceeding six months or both.
And Professor Mwanalushi said the request to extend the forum by two days will be adequate to deal with all outstanding matters on the republican constitution.
He said that there will be no need for any further extension of the process.
38 UPND Members of Parliament had had written to the NDF asking to be guided whether they must stay away or it is mandatory for them to attend.
National Democratic Congress Member of Parliament had also written to the forum asking to stay away because he had not been sworn in.
Meanwhile UPND Leader Hakainde Hichilema yesterday indicated that the party will not impose any sanctions on MPs attending the Forum as that would sway the attention of Zambians on issues affecting the nation.
