TM Property Services has made a complaint to the Office of Fair Trading (OFT) concerning the behaviour of MacDonald Dettwiler (UK) (MDA) in respect of the National Land Information Service (NLIS).

The OFT is investigating under section 26 of the Competition Act 1998. TM Property alleges that the ownership of the hub licence and one of the three channel licences allows MDA to cross-subsidise its NLIS services and operate a monopolistic position.
