My 80 year old mother is going to Ireland for a week on Saturday with my sister - last minute booking. She has been treated for breast cancer in the last 2 years and has a very small tumour in her lung but is generally in good health. Of course insurance companies only see what's in black and white and are offering quotes of about £700. Have just applied online for the new E111 form - due to arrive in 7 days so fingers crossed. Just wondered if insurance necessary if you have the E111 if we are lucky enough to get it back in time? TIA
