Virgin Media is continuing its fight to offer cheaper subscription sports channel access on its broadband TV bundles.

The internet service provider (ISP), which recently gained permission from Ofcom to offer to provide Sky Sports 1 and 2 at a discount rate to its customers, has mounted a legal challenge to the media regulator's wholesale must offer (WMO) model.

Virgin Media is concerned that under the Ofcom system, a payment structure for Sky Sports bundles is not included – threatening its chances of offering cheaper Premier League football coverage in the UK.

The ISP has filed a complaint with the Competition Appeals Tribunal, believing Sky may be able to get around the pricing structure by only offering Sky Sports 1 and 2 alongside other channels outside of the WMO system, such as Sky Movies.

Back in March, Ofcom ordered Sky to offer Sky Sports 1 and 2 to rival broadband and TV operators for £10.63 per subscriber, per channel per month.

However, despite having agreed an interim agreement with its rivals over pricing, Sky is appealing against the introduction of the WMO system.
