The chief executive of Oxfam has been forced out of her £130,000-a-year job after 'serious issues' were raised about her behaviour and decision making.
Dr Halima Begum's position was declared 'untenable' by the charity's board of trustees following an 'irretrievable breakdown in its trust and confidence' about her ability to do the job.
It came after 70 members of staff signed a letter calling for an investigation into Dr Begum's conduct.
Several employees are also said to have resigned after falling out with her, The Times has reported.
Oxfam confirmed its board of trustees commissioned the review to examine 'concerns raised about the leadership, conduct and approach' of Dr Begum.
It was conducted by legal firm Howlett Brown between November and December this year and drew on testimony from 32 current and former staff as well as documentary evidence, the charity added.
The investigation found 'serious issues' with her leadership, as well as alleged 'breaches of organisational processes and values'.
Oxfam has said Dr Begum, who had been in the role for two years, has already left the charity and the decision to discharge her was passed last week.
Jan Oldfield, Oxfam's current chief supporter officer, will now take on the role of acting chief executive while a permanent replacement is found.
Dr Begum's departure is the latest scandal to rock Oxfam following a difficult few years for the charity.
Financial figures released earlier this month showed that its profits from shops had fallen by two thirds over the past three years.
It also announced it would be making 250 of its 2,100 UK staff redundant earlier this year to save £10.2million from its wage bill.
Meanwhile, in 2023 Oxfam came under fire for issuing a bizarre 'inclusive' language guide to staff.
The 92-page report warned against using 'colonial' phrases such as 'headquarters', and suggested the term 'local' could be offensive.
Workers were told 'parent' is often preferable to 'mother' or 'father' and terms such as 'feminine hygiene' should be dropped.
The guide even suggested that 'youth', 'the elderly' and 'seniors' should be avoided - to afford respect and dignity.
Responding to the criticism, Oxfam said in a statement: 'This guide is not prescriptive but helps authors communicate in a way that is respectful to the diverse range of people with which we work.
'We are proud of using inclusive language; we won't succeed in tackling poverty by excluding marginalised groups.'
The Daily Mail has contacted Oxfam for further comment on Dr Begum's departure.
