A press release from Cambridge Analytica and parent company SCL Group has stated that all the firm's operations have ceased. Insolvency applications have been filed in the UK and bankruptcy proceedings will soon commence in the USA. The company's closure has been attributed to "damage caused to the business by the unfairly negative media coverage" in relation to the ongoing Facebook data scandal.
