If you've planned a trip to the USA anytime soon, you might want to check your passport is up to date...
Owners of the old style passport are being warned they will be refused entry to America, when travelling from a Visa Waiver Programme country, including the UK, if they don't update to an electronic passport (one which has an embedded electronic chip).
E-passports were introduced in October 2006, and with British passports only lasting a maximum of 10 years, those affected would have to have been issued one between May and October 2006.
