The prime minister of Fiji Commodore Frank Bainimarama says he does not lose any sleep over the United Front for a Democratic Fiji.
The largest opposition grouping in Fiji has kept up its attack on the regime since the beginning of the year and maintains the 1997 constitution is the country's rightful one.
The group includes three of Fiji's four political parties and one of Fiji's umbrella unions, the Council of Trade Unions.
Commodore Bainimarama told Radio Tarana the UFDF was made up of political has-beens who are wasting their time pressuring the government.
"These people are only in bed together now because they have a common opponent and that's me. And we all know that saying, my enemy is my friend. But how is that a genuine basis for taking the country forward?"
Commodore Bainimarama says they are against the constitution because they won't be able to compete on the level playing field his government's constitution provides.
