Their roles are disappearing along with that of editor of the Basingstoke Gazette, whose editor Mark Jones recently left to take up a charity PR role.
A message sent from Ian to Newsquest Hampshire staff read: “Due to the proposed introduction of the new editorial system Knowledge, it is proposed to change the way in which content gathering and sharing takes place in the Hampshire Newsquest region.
“As part of those proposed changes it is proposed to bring control of all publication titles within Hampshire Newsquest into the structure based at Redbridge and to streamline the running of head office newsroom functions.
“If the proposals are agreed the posts of Editor at both the Hampshire Chronicle and Romsey Advertiser would not be part of the new structure.
“The vacant editor post at the Basingstoke Gazette will also not be filled as part of this proposal.”
Keith, 58, had been shortly due to celebrate ten years as editor of the Chronicle, having taken over the role in March 2005.
In 2009, he scored a notable scoop after spotting the former 1960s chat show host Simon Dee sitting outside a coffee bar in Winchester and persuading him to give his first press interview for more than 20 years.
It also turned out to be his last interview as Dee died a few months later from bone cancer.
Mark, who had been in charge at Basingstoke since February 2002, has been appointed director of fundraising and communications for the Ark Cancer Centre Charity, based at the town’s hospital.
He moved to Basingstoke as deputy editor in February 1997, after spending six years at the Daily Echo where he was chief crime reporter and later assistant news editor.
A formal consultation period with those affected has now begun with the outcome due to be announced on Thursday 5 March.
Newsquest has declined to comment further on the proposals.
