LONDON — The BBC is in a bind after opponents of late British leader Margaret Thatcher pushed the song "Ding Dong! The Witch is Dead" to the top of the charts.

An online campaign to drive the "Wizard of Oz" ditty to the No. 1 spot on the U.K. singles chart was launched by Thatcher critics shortly after the former prime minister died of a stroke on Monday. She was 87.

Normally, a top position on the charts guarantees a song airtime on the BBC, but some called on the broadcaster not to play the song.

John Whittingdale, a lawmaker from Thatcher's Conservative party, told the Daily Mail newspaper that many would find the song "deeply insensitive."

Messages left for the BBC weren't immediately returned Friday.
