Mr Mack Manu, Western Regional Chairman of the NPP, has said many of the party's campaign promises during the 2000 electioneering campaign had been fulfilled.
He said this accounted for "the string of defeat of the NDC" in the recent by-elections.
Addressing the regional executive committee meeting at Sekondi on Saturday, Mr Manu predicted a landslide victory for the party 2004 elections and said the party would capture not less than 140 parliamentary seats.
The meeting, which was attended by constituency chairmen, some parliamentarians and regional executive members took stock of the party's performance in the region and discussed strategies to enhance its chances in the next elections.
The NPP Regional Chairman called for a vigorous campaign and membership devoid of insults, personal attacks and character assassination.
"We shall campaign on our laudable policies and achievements in infrastructure development and good governance, peace and higher productivity".
Mr Manu said primaries for the selection of parliamentary candidates in the region would begin soon.
Papa Owusu Ankomah, Attorney General and Minister of Justice, stressed the need for co-ordination between the various structures of the party to strengthen its position on the ground.
"From their recent pronouncements it is clear that NDG leaders are doing everything possible to undermine the government since they have now recognised that their second defeat will send the party into the wilderness for a very long time".
Papa Owusu Ankomah, who is the MP for Sekondi, said the NPP would appeal to the electorate to give it the mandate to rule since no government could deliver without solid support.
He admitted that the government had not found things easy due to the situation it inherited but said it had done better than the opposition.
The Attorney General advised against petty squabbles among party members, adding that, the government's attention would not be diverted from the goals it had set itself.
