Expletive-ridden rant stokes tensions within Labor party

SYDNEY - Leadership tensions within Australia's ruling Labor party erupted on Sunday with the release of a video showing ex-prime minister Kevin Rudd on an expletive-ridden rant about a Chinese interpreter.

The two-minute video, uploaded onto YouTube by a user calling themselves "HappyVegemiteKR", shows an irate Rudd trying to record a message in Mandarin and railing against the "d##khead in the embassy" who wrote the text.

"This f##king language, he just complicates it so much. How can anyone do this?" Rudd, a former diplomat who speaks Mandarin, shouts as he slams his fist on the table in front of him.
