“There's a lot more activity and galleries to go to in London," says the New York-based art adviser Candace Worth, who specialises in the “primary” market of new works bought directly from dealers. “Paris has never been as transactional for me. There's a greater concentration of galleries I want to deal with in London.”

“There's always talent coming out of Britain,” Worth points out. “People are picking up British artists from the art schools.”
