Big Technologies plc chair Alexander Brennan is to step down as non-executive chair with immediate effect.
Sara Murray OBE is embroiled in a £320m High Court battle with Big Technologies plc after it dismissed her from the position of CEO in March. Murray’s assets have been effectively frozen during the case; and two weeks ago Big Technologies accused her of forgery and deliberate falsification of documents to push through the company’s £577m IPO in 2021. You can read full details of the accusation here.
Meanwhile a group of former shareholders are suing the firm as they claim Murray effectively pushed them out via an earlier MBO.
Late last week, Murray was part of a group of current shareholders seeking to remove Brennan from the board and replace him with James Graham Matheson.
“Having led the board as interim chairman and then chairman, including during the period of the investigations undertaken by the company related to the removal of Sara Murray as CEO, Alexander has made the determination that it is in the best interests of all shareholders if a new director, independent of the investigations, were to lead the company’s efforts to resolve the protracted litigation against Sara Murray and associated parties,” a notice to the London Stock Exchange read.
Sangita Shah will take over the role on an interim basis.
Shah said: “On behalf of the board, I would like to thank Alexander for his integrity and his conduct, at the core of which has been a steadfast adherence to the highest standards of governance in the discharge of his duties, notably this year.
“This has been a difficult time for the company, and we are grateful to Alexander for his consistent dedication and professionalism.
“The board await confirmation that our offer of mediation will be accepted by Sara Murray to enable the company to progress to constructive settlement discussions.”
