Video: RHI scandal - 'Public need to have confidence in politics', says Sinn Fein's Michelle O'Neill
Stormont has been rocked by allegations in the so-called 'cash-for-ash' scandal which could cost NI taxpayers £400m.
Sinn Féin, the DUP's partner in the Northern Ireland Executive, has said there should be an independent investigation.
The party's Michelle O'Neill said: "The public are sick, sore and tired of being drip-fed information. They deserve answers."
