Two weekly editors posts have been cut as part of a reorganisation at South West Wales Publications.
The Journal is currently edited by David Hardy, while the Star is edited by Andy Pearson.
The company is in the process of restructuring and streamlining its editorial operations, and it is possible that they will be redeployed.
As part of the changes two assistant editor posts will be created at the weekly titles. The post of deputy editor at the Evening Post will not be filled, but Cathy Duncan will continue as assistant editor.
David has edited the Carmarthen Journal since October 2003 and had previously worked at the Gloucestershire Echo, joining in 1990 as a sub-editor before becoming assistant editor.
Andy has edited the Llanelli Star since October 2002, when he replaced Robert Lloyd as part of an earlier reshuffle.
He was previously features editor at the South Wales Evening Post and has also worked for the Western Mail.
Last month South Wales Evening Post editor Spencer Feeney was appointed to the expanded role of editor-in-chief of South West Wales Publications, with overall responsibility for all SWWP editorial affairs.
The company is proposing to centralise some of its operations in Swansea, with staff transferring from Carmarthen and Llanelli.
Managing director Chris Rees said consultations with staff were continuing and were due to come to an end in the next fortnight.
The proposals follow an editorial review by SWWP and consultants for Northcliffe Newspapers’ Aim Higher programme.
