Former Minister Andrew Bayly says a complaint was laid about him laying a hand on a staffer. 

He says it was during a work discussion he's called 'animated' last Tuesday.

He's apologised to the staff member, and resigned as ACC and Commerce and Consumer Affairs Minister, but he remains the MP for Port Waikato. 

ZB senior political correspondent Barry Soper says Bayly's got a reputation as an 'interesting' character - but he owned up to his mistake.
