Scottish entrepreneur Sir Tom Hunter is weighing up a bid for Dobbies Garden Centre, which received a £155m offer from Tesco earlier this month.

Sir Tom has appointed investment bank NM Rothschild to advise him on a potential bid for the garden centre chain, according to reports in the Sunday Express.

Last week, Sir Tom increased his stake in Dobbies to 25.6% in an attempt to block Tesco's takeover, but Tesco responded by sending out an offer document to shareholders which cut the acceptance level needed from 75% to just 50%.
