Ms Archer has resigned for personal reasons

Robyn Archer, the Australian singer and actress, was appointed artistic director of the Liverpool Culture Company in 2004.

She has previously directed festivals in Canberra and Adelaide, and is also a successful writer.

A statement from the city council said Ms Archer, who is currently on leave, had resigned for personal reasons.

Councillor Warren Bradley, Leader of Liverpool City Council, said: "Robyn Archer is one of the world's most foremost and respected festival directors with more than 10 years' experience in arranging large-scale international events.

The city's programme for 2008 will be unveiled in November

"It is a matter of great regret that she has decided that she can no longer continue in her role here for personal reasons.

"I would like to thank her for her work in Liverpool and wish her well for the future."

Professor Drummond Bone, Chairman of the Liverpool Culture Company, said: "Robyn has worked very hard in collaboration with the cultural organisations throughout Liverpool to create an innovative artistic programme not just for 2008 but for the years leading up to Capital of Culture status.

"We will all miss her exceptional drive and enthusiasm."

'Much regret'

The Culture Company's Executive Group has announced detailed plans for developing the artistic programme for 2008 will be made in consultation with the major cultural institutions and community arts organisations in Liverpool.

A statement from Ms Archer said: "I have thoroughly enjoyed my time working with a great artistic team at the Culture Company and I would also particularly like to thank all the major cultural and community organisations who are at the heart of delivering a great Capital of Culture in 2008.

"I very much regret leaving Liverpool at this stage but I know that there is a fantastic depth of creative talent in the city who will remain in place.

"I am certain that Liverpool will indeed deliver on its promise of a very special Capital of Culture."
