Athens (Reuters) - UK-based fixed-odds betting company Stanleybet said on Friday a court ordered its outlet in Athens to be shut again while a higher tribunal considered its right to compete with Greek gambling monopoly OPAP. Stanleybet opened a store in the Greek capital and one in the northern city of Thessaloniki late last year, but Greek authorities shut them down for not having an operating licence and for violating a law that forbids online betting.
