Hammerson chief executive David Atkins will step down, the shopping centre owner and operator said today.
The company is facing a crisis spurred by coronavirus-induced shop closures and a collapse in rent.
The news comes just weeks after the owner of London's Brent Cross centre and the Bullring in Birmingham saw the collapse of its £400m deal to sell seven retail parks to private equity firm Orion.
Hammerson also owns a 50% stake in the Dundrum, Ilac and Pavillion shopping centres in Dublin, and a 40% stake in Kildare Village here.
David Atkins, who has led the company for over a decade, will step down by 2021 at the latest, Hammerson said.
"The current environment, exacerbated by the impact of COVID-19, is undoubtedly the most challenging we have faced as a business," Atkins said in a statement.
"I feel now is the right time to search for a new chief executive, a person who can not only lead the business as we emerge from this period, but also into its next chapter," he added.
Hammerson has been trimming down debt and fixing its balance sheet by divesting some of its portfolio over the past year.
Like its peers Intu Properties and British Land, it has been hit hard by the coronavirus crisis, which has shut thousands of tenants' stores and forced some into administration.
Many retailers have said they are not currently paying their rent.
