Think the news has been put back to 5.10. Poor scheduling to be honest - they left very little wriggle room for the Derby, even though it started a bit late. Now the Derby coverage seems to be just filling - which seems unnecessary they could of put the News at 4.55 and then have Animal Park.
EDIT: Well now we've lost the coverage and getting some nice music - it's all going wrong! BBC1 seems to have some nicer music now.
