As The Press revealed this morning, City of York Councillor Dave Taylor posted a comment on Facebook stating: "Jack 'Bloodsports' Charlton has died. Good."
Now the party has issued a statement saying that yesterday evening it was made aware of the post on Cllr Taylor's personal Facebook page in relation to the passing of Jack Charlton.
"We would like to apologise to the family of Jack Charlton for any additional upset this has caused at what is clearly an already upsetting time," it said.
"York Green Party will be taking forward our internal investigation in relation to this.
"Cllr Taylor has been an active ward councillor for 14 years and has been re-elected three times which we feel reflects the hard work he has done for the community. We hope people in time will be able to forgive Dave."
