Decision comes amid sex abuse scandal

The BBC was in turmoil on Sunday after its director-general dramatically quit over a broadcast by the British broadcaster's flagship news show that wrongly accused a politician of child sex abuse.

George Entwistle's departure - after just two months in the job - plunges the BBC into fresh crisis after it was engulfed by a scandal surrounding Jimmy Savile, the late BBC star now alleged to have been a prolific sex offender.
