The Carlton Football Club will not cut ties with long-time club sponsor and business associate MC Labour, despite the company being rocked by allegations had links to gangland figures and had been accused of major wrongdoing.

The construction company, which has poured millions of dollars into the club in the past two decades, including a two-year period when Carlton’s home ground, now Ikon Park, was known as MC Labour Park, has been significant contributor to the club, acting as co-major sponsor of the AFLW team for several years.

Carlton still use the company for security and traffic management at Ikon Park for practice matches, open training sessions and AFLW games. MC Labour signs can still be seen in and around the stadium.

Earlier this month, this masthead revealed MC Labour – a major player in Victoria’s construction sector – was implicated in misconduct surrounding the Victorian government’s Metro Tunnel project.

The labour hire firm has been accused of executing “ghost shifts”, when subcontractors file fake invoices for shifts that were never worked and which increase the overall project cost to the taxpayer.

But when questioned on Monday, Carlton said it would not be cutting ties with the company.

“The club does not act on allegations but is aware of and is monitoring the current situation,” it told this masthead in a statement.

A spokesperson for MC Labour stood by the company’s track record and affirmed it would keep working with the Blues.

“MC Labour has contributed to several Carlton initiatives over the years. We also provide traffic management and minor security services for the club from time to time,” the spokesperson said.
