Channel 4 is reportedly looking to drop phone service provider Eckoh following recent allegations over quizzes the company runs.

The broadcaster has already dropped phone-in competitions from its horse racing coverage at the Cheltenham Festival, following the discovery of a "technical fault" on Saturday's The Morning Line competition, which is run by Eckoh.

Richard and Judy afternoon quiz You Say, We Pay, has been suspended, with insiders saying the quiz is likely to be dropped completely, end Channel 4's relationship with Eckoh.

Channel 4 has said it will look for a new partner to provide phone-in services on its racing coverage this weekend.
