The complaint sent by Andrew Sachs’s agent to the BBC in the wake of the Brand/Ross lewd phonecall was not spotted for three days, the BBC Trust said in a report today.

Jonathan Ross and Russell Brand are to apologise personally to veteran actor Andrew Sachs over the offensive calls they made to him during a radio show, sources said tonight.

The BBC was under pressure today to act against presenters Russell Brand and Jonathan Ross after they made a series of crude phone calls to former 'Fawlty Towers' star Andrew Sachs, which were then broadcast.
