Yorkshire Building Society is in advanced talks to buy Chelsea, its weaker rival. Chelsea's members are unlikely to receive a windfall from the deal. Britain's fifth-biggest society has been struggling for months under the weight of mounting losses and spiralling costs of funding.

A Sky spokesman said: "Forcing customers to bail out BT for the mismanagement of its pension fund would be plain wrong.

Mitchells & Butlers, the pub and restaurant operator, launched a fresh assault on rebel shareholders yesterday by effectively sacking the four non-executive directors appointed at the behest of the dissidents.
