I think Dairy Crest would be a good stock to add to Freetrade. They make Cathedral City, Clover and Davidstow Cheddar amongst other products.
Dairy Crest recently agreed to a takeover bid from Canadian company Saputo (another company to add if Canadian shares came to Freetrade) who are looking to expand into new markets which should help both companies grow and expand.
(P.s. Just got access to the Android app and created my account, loving Freetrade so far!)
