The BBC is facing questions over the vocal quality of Mae Muller’s Eurovision performance.

Viewers claimed they could “barely hear her” over the backing music with the singer suffering similar issues in the practices leading up to Saturday’s show. 

Music critics said the song was “excellent” but the “staging wasn’t great” and there were issues with the shots used by the television cameras. It came after Ms Muller suffered technical difficulties during rehearsals.

The London-born singer took to the stage in Liverpool for the Eurovision Song Contest final hoping to finish in the top ten but ended up second from last with I Wrote A Song, claiming just 24 points.

Germany was the only nation to finish below the UK, on 18 points.

The disappointing result comes just 12 months after the UK finished second behind Ukraine when Sam Ryder won over the European audience with his hit Space Man.
