STOCK WATCH

■ OIL rig builder Lamprell left investors spooked after it received a takeover offer far below its market value. It said the offer from Blofeld, its second-largest shareholder with a 25pc stake, ‘is at a very significant discount to the prevailing share price’. The parties have been negotiating for more than two months but pledged to continue talks. Lamprell said any offer needs to include shortterm help to meet a shortfall of £61m. Its shares fell 73.8pc, or 16.3p, to 5.8p.
