What sort of money do you want to spend Berry, does he need any extra kit to go with it, does he have any kit already.
Personally though (budget allowing) and I'm a nikon user, I would look at a
nikon d90, its basically the top consumer (aka prosumer) model and has things like a
vertical grip (used for portrait shots) available if needed (around £150).
The reason I've suggested the d90 is purely due to the fact that it will save you money in the long run

It can use older lenses which don't have the motor's in them like newer ones, you can pick up second hand and often get a better lens (smaller aperture - this is a good thing) for a similar price to a new lens but with lesser features. All of the cheaper models of camera (d70/d80 is an older version of d90) require the motor to be in the lens which means you're restricted to newer lens unless you are prepared to go fully manual.
There are several ways you can get a d90, one is body only (great if you already have nikon kit) for £500+ (depends on store - jessops is £650!), one is a single 18-105mm vr lens kit for around £750 (jessops is £800), there are also some kits with a memory card (sd card) and bag with varying cost etc.
If the budget is a little too high (we all know you like to keep you cash in the wallet Berry

) I would suggest maybe this
type of d5000 kit from jessops (or cheaper if you can find it online), although bear in mind this does have the lens restriction mentioned earlier. A Tamron lens is usually very good quality as is sigma so don't discount those brands.
If you go into a store to buy, haggle the price or stuff for free as jessops are pricey, also try your local small store as they will offer good advice
