A REVISED code for Stormont special advisers is due to be discussed today by executive ministers.
Parties have pledged greater scrutiny of special advisers (Spads) as part of the New Decade, New Approach deal to restore power-sharing.
Concerns over the conduct and accountability of Spads were exposed in the RHI inquiry.
Finance minister Conor Murphy is due to table proposals at today's executive meeting, Deputy First Minister Michelle O'Neill confirmed.
Ms O'Neill said a working group during the talks process on restoring devolution had examined the issue of transparency and accountability in government.
Speaking to BBC's Sunday Politics programme, she said it was a "crucial element" in restoring public confidence in the wake of the RHI scandal.
The Sinn Féin vice-president said she was "very confident" the proposals brought to the executive "will go a lot of the way – if not all the way – to satisfying public confidence around the actual role of special advisers".
But TUV leader Jim Allister has called for changes through legislation rather than a revised code of conduct.
He is bringing forward his own draft law which would make it a criminal offence for a minister or Spad to leak confidential government information to a third party.
The bill would reduce the number of Spads within the Executive Office from eight to four and impose a cap on their annual salaries, which can currently stretch to more than £90,000.
It would also make plain that the appointing minister is "accountable and responsible" for their actions.
"Tinkering with the code may be good in one sense but it's not enough, and it certainly doesn't address the panoply of issues which need to be addressed," he said.
