The promotion expands Halliwell's role to include Trinity Mirror's digital property businesses, which include SmartNewHomes and Email4Property.
Dave Bexon is standing down from his position as Managing Director of Trinity Mirror Digital Property (TMDP) to develop his career ambitions in other areas. However, Bexon will remain closely involved with TMDP in an advisory capacity.
David Black, Trinity Mirror's Group Director of Digital Publishing, said: "With Paul's promotion, we will accelerate delivery of the next stage of our strategy for our online property and recruitment businesses.
"I would also like to thank Dave Bexon for the pivotal role he has played in building TMDP. I am delighted he will be closely involved with the business in the future as an advisor, developing our key account relationships and the next stage of our digital property strategy."
