Teaser 2775: Strictly not

From The Sunday Times, 29th November 2015 [link]

Four celebrities entered a dance competition. Five judges each shared out their eight marks among the four dancers, with each getting a non-zero whole number. Each judge split the eight marks in a different way and then allocated them as follows. Amanda’s marks to Lana and Natasha added to the same total as Barry’s marks to Madge and Paula. Barry gave more marks to Madge than to any other dancer, Charles gave more to Paula than to any other, and Doris gave more to Natasha than to any other. Lana scored more from Edna than from Amanda. All dancers had the same total so the head judge’s scores were used, giving a winner and runner-up.

Who was the head judge, who was the winner and who was the runner-up?
