Lester Mordue, the former MTV programming head, has left Sky's music channels after just eight months.

Mordue was poached from MTV last November to oversee the launch of the three stations - Flaunt, Scuzz and The Amp - but departed the broadcaster last night. Sky has refused to give a reason for his departure.

The channels, which have a market share of just 6% compared to MTV's 58%, are being temporarily overseen by Sky Travel head Delia Bushell until a replacement is appointed.
