The exodus of firms from the London Stock Exchange signals a critical moment for the UK's financial services sector, prompting calls for urgent action from the Confederation of British Industry (CBI).

• 213 firms have left since 2016, with 88 exiting last year alone.
• Rupert Soames, CBI chair, advocates for regulatory changes to attract investment.
• The UK stock market faces increased competition as notable companies like ARM Holdings and Just Eat move their listings abroad.
