Fastest Speeds People Have Been Caught On UK Roads

Just wondering what are some cases of the fastest speeds people have been caught on UK roads and what cars they were driving.

I remember a case the other year of someone driving a modified RS6 going well over 200mph (driver filmed it on his phone).

Vaguely remember a case where an Audi RS5 with a Gallardo V10 engine was caught doing upwards of 170.
