At least three opposition parties have decided to sign a resolution on greater opposition unity, following a meeting on July 28 in which seven opposition parties discussed forming a coalition led by former People's Action Party (PAP) MP Tan Cheng Bock.

The document, which was circulated ahead of the coalition meeting, calls for the opposition parties to resolve to "establish the interests of our nation over and beyond the interests of any one political party, family or individual", according to a copy obtained by The Straits Times.
