Snow has forced Tony Blair to cancel a visit scheduled for tomorrow.
He was due in Newcastle to promote the Tony Blair Sports Foundation, which aims to get youngsters active and help adults become trained coaches.
But the schools he planned to visit were closed today with a strong possibility of remaining shut, and an amateur football club where he was expected was inaccessible.
The foundation said Mr Blair's visit will be re-scheduled.
