As the title says:
i was trying to work out where to put the beetroot and i thought it might work where my raspberries are : they're planted in a square, so there's a huge amount of wasted ground underneath them.
(the ground is far too deep for raspberries too - they only need 5" and the good soil goes down about 18" - I ddin't know I was going to put raspberries there till they arrived!)
Anyway, can anyone think of any problems?  Eg, would the wayward raspberry shoots get in the way?
or do they not like each other? 
it might not get much sun once the canes have thickened out with leaves.

raspberries send suckers up (the following season's fruit canes), and you probably risk damaging them by growing something in their space.  I would leave the raspberries to their dedicated space - they are more expensive than a few beetroot seeds which can be grown in containers if it becomes that desperate

I usually grow lettuce under mine. They quite like a bit of shade in the summer.

I'd be worried about damaging the raspberry roots when harvesting a root crop from underneath them.

Last year I grew cougettes about 2ft  in front of the raspberries,
nay problems at all.
I'd think you wouldn't have any problems with beetroot or as mentioned
lettuce, after all they're very shallow rooting anyhow....slight tug and
out they come.....now something with real deep roots carrots parsnips ect.
 fork .....need I say more.... give it a try....

thank you woodburner and painted lady - mine are glen ample and send up about seventy hundred million trillion suckers every year, so if I have a chance of destroying a couple, that sounds like a great plan to me!   
I have successfully ripped up suckers and re-planted them elsewhere, so that should be okay too.
I have got quite a large square in which the raspberries grow (and the suckers never seem to come up inside the squre, only outside where other stuff is  )

It seems like that might be the only problem (and when I say "ripped up" I mean tugged and tugged and tugged, then re-gripped and tugged some more before they came up....)

lol go for it then. Mine are just planted so a bit more vulnerable! I'm going to try dwarf comfrey under mine, as weed suppressant, and nutrient recycler.
