Former This Morning psychiatrist Raj Persaud has stepped down as host of BBC Radio 4's All In The Mind because of continuing allegations of plagiarism.

The allegations are under investigation by a medical review panel.
It follows the retraction of two articles written by Dr Persaud from separate publications in 2005.
"Dr Raj Persaud offered to stand down from presenting All in the Mind on BBC Radio 4 until this matter is resolved," a BBC spokeswoman said.
"The forthcoming series will be presented by a series of guest presenters including Claudia Hammond and Dr Tanya Byron."
Dr Persaud became a well known TV personality in 1994, alongside presenters Richard Madeley and Judy Finnigan on ITV1's This Morning show.

The psychiatrist, who has nine degrees and has written three psychology books, has attributed the similarities in text between his own work and the work of US professor Thomas Blass to editorial errors.
An article written by Dr Persaud in the February 2005 edition of Progress in Neurology and Psychiatry was withdrawn in September last year, after Professor Blass claimed that "over 50% of his piece was my work".
Dr Persaud apologised for the error. He told the Guardian newspaper in November 2005 that the error occurred "when I cut and pasted the original copy, the references at the end were inadvertently omitted".
A second article - a review by Dr Persaud of Professor Blass' biography of social psychologist Stanley Milgram - was retracted by the British Medical Journal in December 2005 "owing to unattributed use of text from other published sources".
In a letter to the British Medical Journal, published in the Guardian in December 2005, Dr Persaud said that the implication that he sought to pass off others' work as his own was "wholly unfounded".
The ongoing investigation by a review panel from the Institute of Psychiatry, Kings College London, and South London and Maudsley NHS Trust, was launched in December.
The new series of All In The Mind begins on BBC Radio 4 on Tuesday.
