National Grid shareholders have received details of the 2 for 5 Rights Issue of 990,439,017 New Shares at 335 pence per New Share payable on acceptance no later than 11:00am on 11th June 2010.

Shareholders are urged to consider what would happen to the price of shares if there was a major disaster with the pipeline running from Milford Haven, especially in view of the planned high pressure when it is finalised.

This is mentioned in view of the drop in price of BP shares resulting in the undersea oil leak disaster in the Gulf of Mexico (May 2010).
