Guernsey Brewery has had its plans for a Golden Jubilee street party blocked by the island's home affairs committee.It has refused to let the brewer close the seafront for the party because it is concerned rowdiness that occurred during Guernsey's liberation day celebrations could happen again.The committee said it had concerns about the implications for anti-social behaviour, public disorder and under-age drinking. It also cited the disruption to traffic.Guernsey Brewery's tied trade manager Richard Veale told the Guernsey Evening Press he wanted the authorities to compensate for the money it had spent organising the party. He said: "We were trying to make it a big event for everybody. We feel it's an insult to the integrity, experience and professionalism of our licensees and associated partners concerned in organising this event."We are very disappointed that we can't give both the locals and tourists a special Golden Jubilee celebration."Licensees, who had arranged entertainment for the party, have asked for an urgent meeting with the home affairs committee and are demanding its members explain their decision.Local licensee Suzanne Pontin from the Banker's Draught said: "I can't believe they have done this - they are killjoys."The decision on the party came just days after the home affairs committee recommended that applications from pubs to open early for World Cup matches were turned down.
