Margaret Haywood said she filmed because she owed it to patients
A nurse who was struck off for misconduct after secretly filming patients being neglected is considering appealing against the decision.
Margaret Haywood, 58, filmed at the Royal Sussex Hospital in Brighton for a BBC Panorama programme in July 2005.
The Nursing and Midwifery Council said she did not fulfil her nursing obligations and struck her off.
Ms Haywood, a nurse for more than 20 years, has 28 days to take an appeal against the decision to the High Court.
Director of legal services at the Royal College of Nursing Chris Cox said: "The Royal College of Nursing has been providing legal representation for Margaret Haywood from the outset and is very surprised at the severity of the punishment dealt out by the NMC panel.
"Our legal team are working with Margaret to explore the various legal options available to her in light of yesterday's judgment."
The panel at the fitness to practise hearing ruled Ms Haywood, from Liverpool, prioritised the filming and did not fulfil her obligations as a nurse.
Chair of the panel Linda Read said she also breached confidentiality and her misconduct was "fundamentally incompatible with being a nurse".
Ms Haywood had admitted breaching patient confidentiality but denied her fitness to practise had been impaired.
