Radio bosses issued an apology after swearing was accidentally broadcast on a breakfast show.

Listeners complained after the obscenities were heard when microphones were left on as a song played on Southern FM, based in Franklin Road, Portslade.

Station bosses issued a series of on-air apologies.

The pair who were heard swearing were not working for Southern but were in another studio at the same complex.

It is believed a technical fault led to their conversation "leaking" into the signal of the breakfast show's broadcast on Friday.

Listener Linda Phillips, 53, from Hastings, said: “I listen to the breakfast show every day and it’s never been as fruity as this.

“I was shocked to be honest, you don’t want to hear that kind of language at that time of the morning.”

A Southern FM spokesman said: "We apologise unreservedly for any offence caused."

He added the swearing was not intended to be broadcast on air - and categorically denied the pair were employees of Southern, but did not confirm who they were working for.
