Jacob Rees-Mogg’s investment management firm is said to be exploring a sale in a deal that could put him in line for a significant payout. Somerset Capital, which was co-founded by the Business Secretary 15 years ago, is holding talks over a sale as chief executive Dominic Johnson prepares the step down ahead of a potential move into politics. Options being considered include a management buyout or merger with another asset manager, the Financial Times reports. Mr Johnson, a former Conservative Party vice-chair who founded the company alongside Mr Rees-Mogg, will be replaced by chief operating officer Robert Diggle.
