Does anyone know if there are any thornless Roses available in Britain?

I don't think that anything is always thornless, but you can try going to
helpmefind.com, going to their rose section and searching on the class list
"Thornless or almost thornless," seeing what roses you find, and checking
for suppliers in Britain (they list suppliers all around the world).

A few random looks at roses listed under that category shows that Peter
Beales and various other British suppliers have many of them. Good luck!
