CORPORATE executives are being asked to shell out up to $10,000 for intimate dinners with Julia Gillard and Tony Abbott.

The Government and Opposition are hosting boardroom dinners and "business briefings" as they build their war chests for an election expected to cost over $100 million.

Even the Nationals are cashing in on the Coalition's red-hot poll favouritism, with business observers paying a record $8800 for a "premium" ticket to this weekend's federal council in Canberra.

The fundraising blitz comes as MPs from both Labor and the Coalition raise concerns over the deal announced this week to provide "administrative funding" to political parties, at a cost of $58 million over four years.

A number of Coalition and Labor MPs are privately filthy about the deal and are lobbying to have it scrapped. "The public is disgusted with us over this," one Government MP said.

Special Minister of State Mark Drefyus claimed the funding deal, which will be backdated to April 1 and deliver a windfall of around $15 million a year to the Coalition and Labor, would reduce the parties' reliance on corporate funding.

While the polls give Labor little hope of re-election, the Prime Minister and her most senior ministers are reaching out to business, as the ALP seeks to boost its finances to defend vulnerable seats.

Ms Gillard, Treasurer Wayne Swan, Workplace Relations Minister Bill Shorten and Infrastructure Minister Anthony Albanese will be involved in an "intimate" boardroom dinner in Sydney on June 11, part of a host of Labor fundraising events over the next few months.

For $8250 each, corporate executives will be able to spend two days with Government ministers at a Labor "business exchange program" to be held in Sydney in early July.

The program includes "policy briefings and meetings" with senior ministers, a cocktail function and one-on-one meetings in what observers say is the political equivalent of "speed dating".

But senior Labor figures concede that "the hot money is chasing the form horse", with the Liberal Party able to charge a premium for gaining access to the Oppositon Leader and his most senior colleagues.

Mr Abbott and his senior frontbenchers will give a "business briefing", which will be held in Canberra in late June, at a cost of $6600 for the one-day event.

Corporate executives have been invited by the Liberals' federal director Brian Loughnane to meet Mr Abbott and his senior team in the lead-up to "one of the most important (elections) in the history of our country".
