As many as 8 million U.K. workers are at risk of losing their jobs to artificial intelligence (AI) with current government policy, the Institute for Public Policy Research warned.

AI already impacts 11% of tasks done by U.K. staff, a figure that could rise to almost 60% if firms integrate the technology more deeply, the think tank warned in a report published Wednesday. Part-time, entry level and back-office jobs such as customer service are most at risk but higher-paying jobs will increasingly be affected.

The findings highlight the challenges facing the government as it increasingly bets on artificial intelligence to cure the U.K.¡¯s productivity problem. Companies across the board are using AI to drive up efficiency, while the U.K. Chancellor of the Exchequer announced a ?800-million ($1 billion) investment in technology and AI to boost public-sector output.
