A girl i know got stopped for going over 100, the police had been following her for a while, they said the 97mph is the threshold really when it comes to losing your licence. They gave her 2 choices
1. Go to court, they will prove she was doing over 100, and she will lose her licence
2. Admit now that she was speeding and they will record her as only going 97mph and it can all be dealt with out of court with 6 points and a fine.

I think her licence will be ok, just points and a fine

As a general rule if you double the speed limit or go 30mph over it there is a good possibility of a ban, i did 57 in a 30 and got 6 points and £260 fine
