The design collaboration between Giles Deacon and Emanuel Ungaro has ended after two seasons.
Ungaro’s chief executive Jeffry Aronsson confirmed in a statement that the split was a mutual decision.
The French fashion house’s spring 12 collection will go ahead at Paris Fashion Week in October, but the line will be the work of Ungaro’s in-house design team.
Deacon’s departure marks the sixth designer to leave Ungaro’s helm in as many years. The high designer turnover followed the £53m sale of the company in 2005 to internet tycoon Asim Abdullah.
Previous outgoing designers include Giambattista Valli, Esteban Cortazar and Estrella Archs.
It is not known who will replace Deacon at Ungaro.
Deacon will show his ready-to-wear label, Giles, on Monday as part of the London Fashion Week schedule.
A spokeswoman for the label would not comment on the Ungaro-Deacon split. She said: “He is just focussing on his collection ahead of Monday’s show.”
Deacon graduated from Central Saint Martins in 1992 and worked with Jean Charles De Castelbajac for two years before becoming the designer at Bottega Veneta and the Gucci Group. He presented his first Giles collection at London Fashion Week in 2004.
