About 80 Labor MPs and senators (from a total of 103) met at Parliament House yesterday for a planning session that lasted three-and-a-half hours, as speculation continued about a leadership comeback by Kevin Rudd.

Ms Gillard concluded her 20-minute speech _ in which she outlined the government's achievements and plan for 2012 _ by telling the meeting that people joined the ALP for a variety of reasons, but one of the things that motivated all of them was ``building a stronger economy and a fairer society''.

``One of the things people didn't join the Labor Party for is to help the Liberals,'' she warned, according to a caucus source.

She said a ``lack of discipline'' would only help the Coalition and Labor needed internal discipline in the year ahead.

While no member specifically mentioned Mr Rudd, at least three were critical of the government's failure to properly communicate its policies and four were critical of fellow caucus members involved in backgrounding journalists on a potential leadership change.

Ms Gillard said she would not call a leadership vote because there is ``no need''.

`I'm very confident in my leadership,'' Ms Gillard told Network Seven.

While she acknowledged questions about her leadership status were ``endlessly fascinating'' to some, she said she didn't wake up in the morning thinking about it.

Treasurer Wayne Swan told the ABC there were ``one or two individuals out there who are disgruntled'' but the caucus was behind Ms Gillard as leader.

Ms Gillard blamed the global financial situation, profound and rapid change in society and the IT revolution for a rising sense of ``anxiety and hesitancy'' in the community, which was feeding into the political sphere.

Earlier, Workplace Relations Minister Bill Shorten, who was a key figure in toppling Mr Rudd in June 2010, said the hype over the leadership was worse than that surrounding the ``millennium bug'' in 2000.

``It reminds me of the millennium bug in the lead-up to 2000.

``We thought every computer in the world would crash. We woke up the next morning, perhaps some with a hangover, and the computers were still working,'' Mr Shorten told Network Ten.
