Eni is believed to have indicated it is willing to bid 700p a share for Enterprise, but only if it is virtually guaranteed to have the support of the company's leading investors. Most City analysts believe Eni would have little difficulty snatching control of the FTSE 100 oil producer with a bid pitched at more than 650p, particularly given that the shares stood at 430p just a fortnight ago and are at 610p, down 2p, today.
