British dual nationals may be able to use expired UK passports to prove to airlines they are British when controversial new immigration rules come into force, the Home Office has said.

The new rules, coming into force next Wednesday, require anyone coming into the UK with British dual nationality to present a British passport when boarding a plane, ferry or train or to have a “certificate of entitlement” costing £589 attached to their foreign passport.
