Beloved British actress Jean Marsh, who co-created and starred in the iconic period drama Upstairs, Downstairs, has died at the age of 90.

The Emmy-winning star passed away peacefully at her home in London on Sunday, her close friend, filmmaker Michael Lindsay-Hogg, confirmed.

The cause of death was reported as complications from dementia.

Jean, known for her striking features and commanding presence, became a household name in the 1970s thanks to her unforgettable role as Rose Buck – the no-nonsense but warm-hearted head parlour maid – in the much-loved ITV series set in Edwardian England.
