Jeremy was in Chelmsford on 16th because he met Michael Fielder to try and sell the pictures of Sheila. The story about him trying to sell the pictures broke on 17th and I believe he left for St Tropez on 19th or 20th. I haven't heard that he was followed there though?
Well, he was definitely under 24/7 surveillance. 100%.
This means the ST followed him from London on the 16th, hence why they noted “London surveillance ended 1:30am”. Jeremy, being sly, probably thought he’d drive down in darkness because he suspected he was being watched. He isn’t bright at all.
The police definitely had two surveillance officers follow him to St Tropez: they even took photographs of Jeremy running on the beach, laughing, dining out...
I will find the link for you.
I think it may also be in one of the documentaries on YouTube where the police actually say hiw they followed him there and how carefree and happy he was.
I suspect he knew the net was closing in and decided to get a holiday in quickly while he was still free...
