Metro management have refused to comment on why the show was interrupted or why they have suspended the territory's best-known agony aunt.

But almost half the complaints to the licensing authority said the programme had been biased.

Some complainants said the standard was not high enough while others said it should not have dealt with the subject matter raised.

The details of a dispute between members of Tang's family over who should inherit his fortune, estimated at more than $1 billion, have dominated tabloid television, radio and newspapers for months.

Pak's popular late-night programme normally consists of calls from listeners seeking advice on sexual and personal problems.

A letter to Pak, signed by Mr Chan, says her programme, and her boyfriend Paul Tse Wai-chun's show Justice And Compassion, have been suspended indefinitely. Pak and Tse have both been told not to turn up at the station's studios in Whampoa Garden.

Details of their contracts with the station and how much they are paid have not been revealed.

Pak, presenter of Heart to Heart for three years, insisted Tuesday night's programme had not contained any unusual material.

'I don't think I have done anything wrong,' she said.

'I have done what media should have done by giving the public a balanced view,' Pak said.

A music programme has replaced Heart to Heart.
