An Israeli political officer, who was at the centre of an Al Jazeera investigation, has been forced to resign from Israel's UK embassy, a senior official in the Israeli foreign ministry has told Al Jazeera. 
Shai Masot, a senior political officer working at the Israeli embassy, resigned from his post earlier this week, the spokesman said on Thursday.
The investigation, The Lobby, reveals plots by the Israeli diplomat and a British civil servant to destroy the careers of senior politicians.
In a statement posted on his Twitter account on Sunday, the UK Israeli embassy's spokesman, Yiftah Curiel, downplayed comments made by Masot.
