Al Jazeera has uncovered evidence of an Israeli diplomat's involvement in smear campaigns to discredit a British minister and other politicians. Al Jazeera's investigative unit went undercover with an Israeli lobby group for several months. The investigation reveals conversations in which a diplomat plotted to damage the careers of MPs they feel don't give enough support to Israel.
This is an excerpt from a four-part series called The Lobby, which you can watch here.
