Blacks chief executive Julia Reynolds is set to stand down from the outdoors retailer that was acquired by JD Sports Fashion in January.
According to the Independent, JD refused to comment on speculation that Reynolds will leave Blacks and Millets in the coming months.
It is thought that the reason for her departure relates to her changing role - once the integration of Blacks and JD is completed it is thought the role of Blacks chief executive will be different. Reynolds joined Blacks from lingerie retailer Figleaves in August.
Her departure could pile more pressure on JD, which has already closed 80 Blacks shops this year after it collapsed in January.
Blacks collapsed amid declining sales and rising debts.
