Liberal Democrat leader Tim Farron was left red-faced when a controversial rap song blasted from his phone during a meeting.
Mr Farron said he was in a meeting with the head of the local NHS trust at his office in Kendal, Cumbria, when NWA’s "F*** Tha Police" suddenly began playing.
The flustered politician said his children were to blame after setting the album Straight Outta Compton as his ring tone.
This came after he had light-heartedly reviewed the unlikely music choice for music website RAM Album Club.
Recounting the tale during his rally speech at the party's autumn conference in Brighton, he said: "(The album) is deservedly considered a classic, but it's a bit sweary."
To laughter from the audience, he added: "I downloaded the album to my phone but my kids had been mucking about with my phone one morning, and apparently linked my ring tone with my iTunes.
"And so later that day, there I was in my office in Kendal meeting with the chief executive of the local NHS trust, when my phone went off and we were all treated to a quick burst of 'eff the police' - which was lovely.
"Almost a pity I wasn't due to meet the chief constable until later that afternoon."
Mr Farron added that while he admired the rappers behind NWA, their attitudes toward law and order differed from his own.
