I need some worldwide travel insurance for a long trip can any one recommend please
We can recommend Direct Travel insurance. It seems pretty comprehensive, not too expensive and offers different levels of cover including worldwide.
Have a look at this page of The AngloFILE:
Portuguese Insurance: Car, House, Life, Pets
Perhaps one of the companies there could help you.
Thanks for all the useful info everyone. I have been having a problem finding a company that would give me a good quote as I have what they term a "pre-existing condition" I will see how I go with these others.
