UK department store Debenhams has appointed Sergio Bucher, vice-president of fashion at Amazon, as its next CEO.

Sergio, who has served as vice-president of Amazon Fashion Europe since 2013, will join Debenhams in October of this year.

The news comes after the department store's current CEO, Michael Sharp, last month confirmed his departure amid a rise in first-half earnings and sales. Sharp will step down from the board in June.

Sergio counts Puma, Nike and Inditex, where he led the start-up of of its lingerie retail brand Oysho, as previous employers.

He said: "I am excited to be joining Debenhams, with its strong UK heritage, a growing international presence and a track record of supporting and developing brands and designers. I look forward to working with its experienced and talented team to take Debenhams forward to an exciting new future."

Debenhams chairman, Sir Ian Cheshire, said he is "delighted" at the appointment.

He added: "Following a rigorous recruitment process with some exceptional quality candidates, Sergio's wealth of e-commerce expertise, international experience and clear leadership qualities stood out. I am confident we have the best possible person to realise the potential of 'new Debenhams' as a leading international multi-channel retailer with a bright future."

Sergio's appointment comes just a week after analysts at Cowen & Company reported that Amazon is on track to replace Macy's as the number one US apparel retailer by next year.

The online retailer has made an aggressive push into apparel and fashion, and could account for 19% of the overall US apparel market by 2020, up from around 7% today, according to analysts at Morgan Stanley.
