The UK continues to deindustrialize, and London's standing as a financial centre was hurt by 2008, Brexit and superior innovations elsewhere.

Judged as of 2025-12-06. The proposition has two parts: (a) the UK continues to deindustrialize, meaning manufacturing's share of GDP or employment is still falling in recent years; (b) London's standing as a financial centre was damaged by the 2008 crisis, Brexit and superior innovations elsewhere. True: ONS data show manufacturing share or employment still declining up to 2025, and credible evidence (for example Global Financial Centres Index rankings, relocation of jobs and listings, analyses) shows London's standing harmed, with all three causes credibly cited. Mostly true: both parts hold, but one of the three causes is weakly supported. Mixed: one part holds and the other does not, or only one of the three causes is supported. Mostly false: both parts are largely overstated, for example manufacturing output is stable and London's ranking is essentially unchanged, with only minor harms. False: data show reindustrialization and London's standing unharmed or improved.

    “New York City remains at the top of the Index, followed by London, Hong Kong, Singapore, and San Francisco.”

On part (a), the ONS workforce-jobs series shows manufacturing jobs falling from 2,580k in 2023 to 2,555k in 2024 (E9), and ONS reports that manufacturing output fell 0.7% in the three months to October 2025 (E1). Against that, manufacturing output rose in the single month of October 2025 (E6). On part (b), Z/Yen's GFCI 4 from 2008 says London suffered lasting reputational damage to its regulatory environment (E10). Brexit-related harm is documented by the loss of EU passporting (E7), New Financial's finding of damage to the City (E3) and an estimated 40,000 jobs moved to EU hubs (E11). However, no evidence directly supports the third cause, superior innovations elsewhere, and London has stayed second in the GFCI (E8, E12) and remains pre-eminent (E2, E4). This fits the 'mostly true' criterion: both parts hold, but one cause is weakly supported.
