Why Gibraltar isn't just another part of the UK

In Gibraltar, a British Overseas Territory, residents don't vote in UK general elections. That anomaly places it on the UN's list of territories to be decolonized, alongside 17 others. Why doesn't London fully integrate it? The answer has a name: military base and tax haven.

Britain's interest: strategy and money

The Rock is a six-square-kilometre enclave on the Strait. Keeping it as a tolerated colony allows London to enjoy a strategic military base without the constraints of administering yet another region, with a governor and no MPs in Westminster. Moreover, the low-tax regime of online gambling and offshore banking would not survive genuine integration into the UK tax system. The Gibraltarians know it, and that's why they don't ask for it.

The Spanish claim: more noise than substance

Spain bases its claim on the Treaty of Utrecht, which ceded the Rock to Great Britain in exchange for keeping Philip V on the throne. But the argument clashes with the doctrine of Gibraltarian self-determination and with the territory's economic reality. In Spanish public debate, the claim works as a patriotic pacifier: it costs nothing, obliges nothing and looks good at rallies. Nobody explains how a British military base and a tax haven would fit into the Spanish economy.

Meanwhile, Gibraltar remains an uncomfortable reminder that territorial belonging is not always decided by history or the will of the ballot box, but by the interests of whoever is in charge. Does Spain really want Gibraltar, or does it just want Gibraltar not to exist?
