Stuart Polak was born in Liverpool, England.[3] He attended the Childwall Hebrew Congregation, a synagogue in Liverpool, where he was a chazan, or cantor, during the Jewish High Holidays.[3] He took educational trips to Israel from the age of fifteen.[3]
On 3 November 2017, the BBC's Diplomatic correspondent James Landale reported that Polak had accompanied Priti Patel, the Secretary of State for International Development when she had held a series of meetings in Israel in August 2017 without telling the Foreign and Commonwealth Office. They met Yair Lapid, the leader of Israel's centrist Yesh Atid party, and visited several organisations where official departmental business was discussed. Those meetings, and others later, led to Patel's resignation from the Cabinet on 8 November 2017.[7] In 2021, former Foreign Minister Sir Alan Duncan published his diaries, in which Polak featured as a frequent opponent of his fellow Conservative Duncan, allegedly operating in tandem with CFI colleague Eric Pickles to ensure the pro-Palestinian Duncan did not acquire certain governmental positions.[8]
In April 2024 Polak was accused of serving political interests of Israel instead of the interests of his own country - the United Kingdom. Specifically, former Conservative minister Alan Duncan said the following about Polak in his interview: "In my view, I think he should be removed from the Lords because he is exercising the interests of another country, not that of the parliament in which he sits". The Conservative Party launched an investigation into Alan Duncan, despite having no formal complaint, but found no wrongdoing and cleared him in July 2024.[9]
