Have you got a source he is adding to his original submission?
The OS just states the original 2021 8 points.
The only big claim since then has been the aga burns. Believe that was just properganda and not added to the CCRC submission.
At some point in the recent past, Jeremy Bamber has made some kind of press release, or public statement saying that the CCRC are taking too long with his submission.
This complaint was published in at least one national newspaper, and the newspaper did print a response from the CCRC.
It was that response that confirmed that Jeremy Bamber had been submitting more claims, after submitting the initial set of multiple claims.
I don't know how many claims had been made on top of the original multi-claim claim, but I interpreted the CCRC response as meaning more than one extra claim.
You'll have to search for it as I am going from memory. I read it online so it could have been the Daily Mail, as that is usually top of a lot of news searches.
