LWT director of regional affairs Emma Mandley left the channel late last month following the restructure, which saw a complete re-organisation of the division and the creation of several different roles.
Mandley had held the role for around four years, responsible for community affairs projects, CSR initiatives, strategy work and sponsorship.
She was unavailable for comment as PRWeek went to press, but it is understood she lost out on the top regional affairs post, created earlier this year.
Jane Luca was appointed controller of regional affairs in February, in charge of LWT parent firm Granada's entire community relations strategy - a role she took on in addition to her previous post as head of regional affairs for the north-west.
A small number of other staff throughout the community affairs division also lost their jobs.
Luca insisted it was not a cost-cutting move, but a refocusing of resources: 'The review is about being a bit more joined up about what we're doing and co-ordinating at a national level with external partners.
'The review process has meant that rather than each licence having to come up with off-air initiatives, we are now working towards an overall theme, developing a project that's delivered locally,'she added.
Following Mandley's departure, LWT is recruiting for a head of regional and community affairs, to focus less on strategy and more on local implementation.
The new post will report to LWT managing director Christy Sword.
Luca said the review was not linked to the recently announced merger between Granada and Carlton. Granada CEO Charles Allen is set to head the merged group in the same role.
