The European drug regulator has said it strongly opposes the creation of a multistorey erotic centre near its headquarters in Amsterdam as part of city plans to relocate sex workers away from the historic red-light district.The European Medicines Agency (EMA), which moved to Amsterdam from London in 2019 after Britain voted to leave the EU, said it was very concerned about the project, fearing nuisance, drug dealing, drunkenness and disorderly behaviour.
