Badminton England has defended its World Championship preparations after apparent criticism from its top player Nathan Robertson. Robertson and Jenny Wallwork suffered a disappointing first round mixed doubles defeat at Wembley on Tuesday night.

Robertson later said on Twitter: "Today's quote 'World class performance needs world class support' average treatment gets an average outcome. End quote..."

But Badminton Englan chief executive, Adrian Christy, said: "These players have had a fantastic preparation period."
