A national tragedy.
I warn you, this will make you weep openly.
1535 UPDATE: There was a news conference in the last hour. Hugh Sykes was there for PM and will have a report for you in the programme.
And this is just in: Peter Mandelson has told us:
'John Sergeant should not bow out, he has become the people's John Travolta and he should be a fighter and not a quitter.'
