According to Fiji Times Online, this was the decision of the Commonwealth Ministerial Action Group on the Harare Declaration (CMAG) who met in London to discuss Fiji's situation.
Fiji will be suspended from the Commonwealth in September 'if the interim administration does not show "sufficient" progress towards returning the country to democratic rule'.

According to the report, CMAG said it would not suspend Fiji as it was "supportive of the joint mediation of the Commonwealth and the United Nations of the Presidents Political Dialogue Forum (PPDF) process in Fiji".

'It emphasised that such an engagement by the Commonwealth and the UN should be "independent, inclusive, time-bound and without prejudice as to its outcome" and it called on the international community to support this mediation process "politically and financially"'.

'CMAG specified that should "sufficient progress not take place, consistent with the benchmarks set out in the Pacific Islands Forum Leaders Communique", Fiji would be "fully suspended" when the Group next meets in September'.
