Smythson CEO Andy Janowski to leave after the birth of his twins

Chairman and owner Jacques Bahbout will take the reins

The chief executive of Smythson, the leather goods and stationery brand that counts Samantha Cameron as a consultant, will leave the brand after the recent birth of his twins.

Andy Janowski resigned before Christmas and will leave in January to be replaced by chairman and owner Jacques Bahbout.

After more than a year running the brand Mr Janowski decided to leave due to the "recent family situation with the birth of twins" which "prompted his decision".

Owner Mr Bahbout said: “I would like to thank Andy for the work achieved over the last year, helping to lead the transformation of Smythson into a truly luxury leather goods specialist and strengthening the foundation which will allow Smythson to continue double-digit growth and expand into new markets.”

Mr Janowski said: “I am thrilled with the progress that the team has made in advancing the brand and will proudly watch the growth of Smythson in the future.”

Mr Janowski joined Smythson from Burberry where he was chief operations officer and previously worked at Banana Republic and Gap.

The 125 year old Smythson brand, now popular with stars including Kate Bosworth, Miranda Kerr and Florence Welch, recently reported a fall in profit due to the cost of expanding and repositioning to become a global luxury brand.

Mr Bahbout bought Smythson in 2009 and Mr Janowski joined the board as a non executive in 2010 and as chief executive in May 2012.
