BrewDog co-founder James Watt is facing formal complaints to the UK's Information Commissioner's Office (ICO) over his efforts to buy back the company he co-founded.

The regulator is examining allegations that Watt contacted former shareholders directly as part of a fresh bid to regain control of the Scottish craft brewer, raising questions about data protection compliance in the takeover process.

The complaints emerge as Watt seeks to reverse the company's recent acquisition by a US-based firm.

The move follows a period of significant turbulence for BrewDog, including the immediate resignation of its chief executive earlier this year, which ended a tenure of less than twelve months.

The leadership change occurred shortly after the US acquisition was completed, signaling ongoing instability within the organization.

The ICO's involvement adds a layer of regulatory risk to Watt's campaign.
