Russell McVeagh says it is investigating a complaint which relates to a partner making inappropriate comments while attending a client event under the influence of alcohol.

In a statement, Russell McVeagh Chair Malcolm Crotty has confirmed that a partner has been restricted from the workplace while an independent investigation is underway.

“The seriousness with which we are treating this investigation confirms our commitment to building a culture of trust and transparency," he says.

“Everyone in the organisation knows what is expected of them and we will not tolerate any inappropriate behaviour.

"We expect to make a more detailed statement following the outcome of the investigation in the next 10 working days."
