Blue badge new criteria?

Hi all,
Just heard a brief radio report on changes to DLA Blue Badge criteria as “50% abuse of system” suspected.
Anyone else seen/heard this?
Thanks

Hiya,
This is BBC link for article:

It seems issuing of BB now going to come under council control rather than GP. Wondering where medical expertise is going to come in there?
