Antitrust

Definition of 'Antitrust'

The US term for policies designed to restrict anti-competitive monopolies, and promote competition. The main bodies responsible for the policies are the US Department of Justice and the Federal Trade Commission.

In the UK, the Monopolies and Mergers Commission (MMC) now replaces the Competition Commission (CC), which has the power to judge whether any particular monopoly or merged company has been acting in an anti-competitive way.
