The sale of loss adjuster GAB Robins has run two months overdue, fuelling speculation that due diligence has thrown up problems.
Staff initially expected the announcement to be made at the end of July.
However. one senior staff member, Clive Nicholls, said this week the new parent company would be revealed tomorrow.
US financial group, GE Capital, is touted as the possible buyer by industry sources.
A spokesperson was unwilling to comment on the sale but admitted it was dragging on far longer than expected.
GAB Robins has been on the market since February after its Swiss parent – Societe Generale de Surveillance – decided to asses its worldwide operations following poor results.
