Government has said the opposition New Patriotic Party (NPP) has no moral basis to demand the resignation of the embattled National Security Advisor for alleged unsavoury comments made about striking public workers.

Deputy Minister for Information and Media Relations, Felix Kwakye Ofosu has suggested that if the NPP is without sin, it should cast the first stone at the Brigadier-General (rtd), Joseph Nunoo Mensah.

The NPP issued a statement Monday, calling on the 1979 military junta Chief of Defence Staff to resign for "highly inappropriate" and "distasteful" comments made over the week-end at a public ceremony.

The party said it was disappointed that the disrespectful comment was also made in the presence of the President amidst laughter and wondered why President John Mahama did not condemn the statement when he had the chance to speak at that ceremony.

The retired Brigadier General, Nunoo Mensah noted in his speech that “every Tom, Dick and Harry gets up and is calling for a strike. If you don’t want the job, Ghana is not a police state, take your passport and get out of this country... “If you can’t sacrifice like what some of us have done then get out. If the kitchen is too hot for you, get out”.

Public condemnation and calls for his resignation has been unending.

But speaking to Joy FM's Top Story, a Deputy Minister for Information and Media Relations pointed out the NPP's demand smacks of inconsistency and was based on convenient politicking.

Felix Kwakye Ofosu recalled how the NPP "refused doggedly" to sanction their General Secretary Kwadwo Owusu Afriyie after he was convicted of criminal contempt for making disparaging comments about Supreme Court judges during the hearing of the Election Petition last August.

Recalling that the party tops a recent report on the abusive use of language in the media, Kwakye Ofosu charged NPP to "demonstrate that they are against vituperative language".

"Those who call for equity must come with clean hands", he demanded.

Falling short of condemning Nunoo Mensah's statement, he said in view of the inconsistency in the position of the NPP, government found it "difficult to place any weight on the demand."
