Brexit or not?

 After reading Nolan Jazimreg's book 'BREXIT The Great British Tax Avoidance Swindle' I did a little research using Google Gemini. I asked Gemini to construct tables of the net worth of pro and anti Brexiteers in Parliament before and after Brexit. You should remember that an AI can make mistakes, but I found the results to be informative.

Prominent Brexiteers and those against Brexit

I asked Gemini to research a similar table for the most vociferous Anti-Brexiter MPs. I expected their fortunes to increase dramatically until 2020, they would be fools not to take advantage of each Brexit 'deadline', but grow more slowly afterwards.

Politician	Estimated Net Worth (2016)	Primary Source of Wealth/Assets	Current Status / Affiliation (Feb 2026)	Estimated Net Worth (2026)	Notes on Wealth Growth
Nick Clegg	£1m – £2m	MP salary; property in London & Spain.	Private Sector (Hiro Capital)	£25m – £35m	The most dramatic growth. Earned c. £15m from Meta (Facebook) share sales alone after joining in 2018.

Anna Soubry	Under £1m	Legal (Barrister); MP salary.	Corporate Advisory	£1m – £2m	Shifted to corporate legal and advisory work after losing her seat in 2019.

Gemini reported: "As you suspected, many high-profile 'Remainers' saw a significant surge in their net worth between 2016 and 2020. This was often driven by a pivot into the private sector (specifically global finance or tech) immediately after the referendum, where their "inside knowledge" of the UK's exit process was highly valued. However, for those who stayed in frontline politics (like Sir Keir Starmer), the growth has been steadier and more tied to traditional property appreciation."

So what would have happened if we had remained in the EU and these MPs faced the EU Anti-tax avoidance directive (ATAD)?
