After the best day ever in London yesterday, today we have the worst.
We are all in shock, but there are a few positive things to say:
1. We will NOT be cowed by terrorists. London is, and will remain, the great capital city that it truly is.
2. The casualties are appalling, but we must be grateful that it wasn't worse than it is.
3. The emergency services have been marvellous.
My thanks to everyone who has phoned and written today - your concern is a signal of the solidarity we all feel in the face of such horrific and cowardly attacks on innocent civilians.
