BBC presenter Clare Balding has had to apologise to Grand National winning jockey Liam Treadwell for making a "humiliating" jibe about his teeth.

The jockey should have been basking in the glory of his victory but, instead, Balding embarrassed him by making him smile for the cameras and saying his teeth were "not the best in the world".

It was a pretty crass remark but it led to a good headline in The Sun - "Grand Gnashional".

Here's my prediction: There'll be a race between PR companies representing private dental practices to sort Liam's gappy teeth out.

He'll have the straightest smile in the weighing room before you know it.
