An opinion poll shows a majority of Greeks are dissatisfied with the new government's performance, and half want it to compromise with its European creditors if current tortuous bailout negotiations reach an impasse.

The poll, carried out by ALCO for the Proto Thema Sunday newspaper, found 52 percent were not satisfied with the government's performance since its Jan. 25 election win, compared to 39 percent who were. If creditors don't accept Greece's proposals, 50 percent want the government to compromise and 36 percent want a rupture.

Greece has grown isolated in negotiations. With coffers running dry, it had until April 30 to come up with acceptable reforms so creditors can unlock the final 7.2 billion euro ($7.8 billion) bailout installment.

The poll had a margin of error of 3.1 percent.
