This is an urgent wake-up call for anyone travelling to Europe this summer - there is a way to get totally free medical cover for you and your family in 27 European countries.
It is called the EHIC, or European Health Insurance Card, and there's more to it than meets the eye. If you've already got one, beware - many older ones are no longer valid.
The totally free card is valid for three to five years and entitles you to free or discounted medical treatment in state-run hospitals in EU countries, plus Iceland, Liechtenstein, Norway and Switzerland.
