Iris Robinson probe: Assembly committee report says 'serious breach'

Iris Robinson committed a "serious breach" of the Northern Ireland Assembly's code of conduct, an investigation has found.

The assembly's Committee on Standards and Privileges report follows BBC Spotlight allegations four years ago.

Alastair Ross, chair of the Standards and Privileges Committee, said the committee felt it was a serious breach and ensured an independent investigation took place.

The investigation found First Minister Peter Robinson did not breach the code.
