A luncheon last Thursday between three old Labor allies -- former Premier Wayne Goss, and colleagues Kevin Rudd and Wayne Swann -- has drawn criticism from the state government.

The three, dubbed "the Troika", were spotted enjoying a leisurely lunch together at the Grecian Cafe in Hamilton, Brisbane on the afternoon Governor Leneen Forde re- opened state parliament.

It is understood Mr Goss and Mr Rudd left the restaurant at around 4 pm.

Mr Goss, his former deputy Tom Burns, and some former Labor ministers last week were criticised for not attending the re-opening, during which Mrs Forde outlined the Borbidge government's legislative program.

Although Mr Swann and Mr Rudd are now private citizens, Mr Goss is still a parliamentary backbencher on the public payroll.

Treasurer Joan Sheldon said the former Premier's action represented "a slight on the Governor, and a slight on the people of Queensland".

"And it's a bit petty", she said.

Mr Swann, a former ALP state secretary, recently lost the federal seat of Lilley at the federal election. Mr Rudd, who ran the government's Office of Cabinet, unsuccessfully contested the seat of Griffith.
