Got a couple of nursing friends who are heading over to the UK next year (April-May-ish...) & are keen to visit a nursing expo or two to make it a tax-deductible trip

Can you help with some contacts or websites to find out what's on & where? They've not yet worked out an itinerary & are planning to work things around what's on, so any tips would be welcome.
Ta muchly
