(a) State and explain what offences have been committed in the following events at the Eatmore Supermarket.

(i) John, an assistant in the florist's section picks some wild roses growing on a nearby common and sells them in the florist's section and keeps the proceeds of sale.

(ii) Maisy, a shelfstacker, finds a handbag in a recently used but otherwise empty store trolley. Maisy keeps the handbag and the money it contains.

(iii) Ernie takes some items of food from the shelves and places then in his trolley intending to pay at the checkout. He also takes three tins of meat paste and puts them in his pocket: he does not intend to pay for the meat paste. The store manageress sees what Ernie has done and detains him before he reaches the checkout.

(b) John is a director of Derwent plc, a listed company. The board of Derwent received at its last meeting a report by Joe, the Finance Director of Derwent, that Derwent's profits would be up by 30 per cent and that this would appear in the press report on the annual accounts in two weeks' time. Next day John told Sid, his golfing companion, that Derwent's profits would be up by 30 per cent, and Sid bought shares in Derwent. On the same day, Sid said to his daughter Kylie, a hair stylist with her own salon, that she 'really ought to have bought shares in Derwent because they seem to be a good thing'. Kylie also bought shares in Derwent. When the results were announced, the shares in Derwent increased in price by 10 pence per  share.

Explain to John, Sid and Kylie the possible results in legal terms of their activities in regard to Derwent's shares.
