Sir Tom Hunter, the owner of Wyevale Garden Centres, has further increased his stake in Dobbies Garden Centre.

The increase, from 20% to 26%, follows news yesterday that Tesco had extended the deadline for shareholders to accept its recommended cash offer for Dobbies to 8 August.

Tesco tabled the 1,500p-a-share offer last month but yesterday revealed that it had persuaded independent shareholders holding just 1.4% in Dobbies to accept its offer.
