Jose Mourinho was mobbed on his arrival at Lisbon airport

Pedro Santana Lopes was appearing on the SIC channel when the programme was interrupted to show Mr Mourinho's arrival at Lisbon airport.

"Do you think this justifies [the interruption]?" he asked on air. "This country is going crazy.

"I am not going ahead with the interview. People have to learn."

Mr Santana Lopes, the former conservative leader, was appearing on the programme on Wednesday to discuss his Social Democratic Party's election plans.

"I like Mourinho but I won't be interrupted by the arrival of a football coach," he said later.

"There are rules."

The TV station said Mr Santana Lopes's decision to walk out of the broadcast had been "disproportionate".

The self-styled "Special One" was arriving home after his shock exit from Chelsea Football Club last week.

However his homecoming is expected to be temporary as he said he is not interested in coaching in Portugal again in the near future.
