Former New South Wales Labor Minister Eddie Obeid has been recalled to the Independent Commission Against Corruption (ICAC) today to face more questioning about a mining licence.

The ICAC is investigating two coal mining licences approved by former mining minister Ian Macdonald.

A public inquiry into the Mount Penny licence has finished, but Eddie Obeid has been recalled to respond to evidence given by businessman Alan Fang.

Mr Fang told the inquiry that when he expressed interest in investing in projects in Australia, Ian Macdonald set up a meeting with Eddie Obeid.

Mr Obeid will return to the ICAC today after a complaint was raised on his behalf that the evidence given by Mr Fang had not been put to him.

In a statement, the ICAC said: "Irrespective of whether or not it was necessary to do so, the commission has decided that Mr Obeid Sr should be recalled so that these issues can be raised with him by counsel-assisting the commission".

Ian Macdonald is accused of rigging the Mount Penny tender to benefit Eddie Obeid and his family.

Mr Obeid has denied knowing properties bought by his sons were covered by a new mining tenement.
