I've just ridden past a police/GLA operation on Leasowe Shore. There's about fifteen police officers (two mobile camera vans) and around eight GLA people waiting for the cocklers to come back onto the land.
Two vehicles immediately headed for the shore and were pounced upon by the police & GLA who questioned them and took photographs. They are now awaiting the remaining cocklers to head in... they didn't look to be in any hurry though.
no doubt there'll be loads of cocklers there this weekend with the spring tides. last time they left a right mess with leaving 100's of bright orange cockle bags everywhere. i found some washed ashore as far up as seacombe months later
