The President of the Democratic Party, Makituti Tongia, says they will not enter into any coalition to form government after the forthcoming election.
He says the message from the party's grassroots supporters is that the Democrats should not form any affiliations with rival political parties after the September 7 election.
Mr Tongia, who dismisses rumours of a split within his party's ranks, says the Democrats see coalitions as the main reason for the political instability of recent years.
He says the perception is that for their rivals, the Cook Islands Party, to beat the Democrats, they have to divide them, but the party is united and seeks a clear mandate from voters to govern again.
"We're not having any more coalitions. It's politically unstable. We've gone through it for the past four years and it hasn't created stability for the country and for the party support."
