Will Chase, the potato farmer who owns Tyrrells crisps, is planning to sell a stake in the company for more than £20m.

Chase has appointed corporate financiers BDO Stoy Hayward to carry out a strategic review of the company after receiving a number of unsolicited approaches, according to the Daily Telegraph.

First round proposals from a small group of private equity firms were due in last week and meetings with those taken through would take place over the next few weeks, the paper added.
