Yesterday National Grid held its Annual General Meeting ('AGM') and an
Extraordinary General Meeting ('EGM').

The ordinary resolution at the EGM sought approval for the acquisition of
KeySpan Corporation.  Completion of the acquisition is conditional upon the
fulfilment of certain anti-trust and regulatory consents and approvals in the US
