The chief executive of Barnet, Enfield and Haringey Mental Health trust has left the trust after less than three months in the job, HSJ has learnt.

Interim chief executive Martin Brown, who is an associate director at consultancy firm Mental Health Strategies and former head of health at the Audit Commission, replaced former chief executive John Newbury-Helps who left the organisation in July. Mr Brown was expected to remain in post for six months until December when the trust had hoped to appoint a new permanent chief executive. (news, page 13 13/9/07)

However, the trust issued a statement last week which confirmed that trust had 'agreed to part company' with Mr Brown, although the organisation refused to give any further details as to the reason for his unexpected departure. Mr Brown also declined to comment on why he was leaving the trust.

The trust has appointed Maria Kane, executive director of corporate development, as acting chief executive-the third in as many months.

The organisation has seen several senior staff leave ahead of a reorganisation of its executive board as it prepares for its application to become a foundation trust.

In September the trust's nursing director Bernadette Hennigan left by 'mutual agreement' after three years in the job.

Last month the organisation's human resources director Janet Lynch also left to become the new HR director at East and North Hertfordshire trust. The trust has not yet appointed a new HR director, and Ms Hennigan has been replaced by interim nursing director Paul Farrimond, from North Yorkshire and York primary care trust.

Barnet, Enfield and Haringey Mental Health trust is also recruiting a new medical director following Rosalind Furlong's announcement that she will retire at the end of the year.
