Deputy Premier Paula Cox has confirmed she and other Cabinet members signed a loyalty oath to Premier Ewart Brown in the run-up to the leadership debate sparked by angry MPs.

And she confirmed she is still interested in running for the leadership but it was not clear when.

Party loyalists have been on the talk shows this week denouncing news reports revealing loyalty oaths as "lies" but Ms Cox admitted signing one this week.

She told the Everest DeCosta talk show: "When I chose to run for the leadership and participate in any leadership bid it won't be by any covert means or by stealth."

Instead a resignation would signal her intent, said Ms Cox.

"I don't believe you sit at the table and at the same time seek to destablise by way of stealth, especially at this juncture."

She said there was no need for an oath of allegiance as Ministers were bound by certain oaths.

"But it is out in the public domain that there was a request, I was the only one who had a caveat on mine."

She said when Labour Minister David Burch invited her to sign "an oath" or "a commitment given all the talk and hoopla I said so long as I put it in writing that it is very clear that the summary does not mitigate against the importance of Wednesday night's caucus meeting that there is a firm, frank and unfettered discussion."

This week MPs and Senators debated Dr. Brown's leadership but he emerged still in place.

It's thought MPs seeking to oust Dr. Brown will seek to undermine him in Parliament possibly through a 'no confidence' vote.

They believe he is vindictive, embarrassing and a threat to democracy.

And there is mounting anger of his recent attempt to fire Civil Service head Kenneth Dill.
