Addleshaw Goddard has appointed Jon Tweedale as Co-Head of International Arbitration to lead the practice alongside current practice head, Simon Kamstra.

Based in the London office, Tweedale has a broad practice, which includes energy and life sciences.  His diverse client base includes the oil major BP and the Islamic Republic of Pakistan.  

He was recognised in Who's Who Legal Arbitration: Future Leaders 2019, which identified him as a "rising star" and a "leading practitioner in the field who enjoys as strong international reputation for his specialist knowledge of arbitration".  He was also included in the Legal 500 International Arbitration Powerlist UK 2019, which showcased 200 of the UK's leading arbitration practitioners.

Tweedale was recruited from Allen & Overy in 2007 as part of Addleshaw's drive to develop a specialist team of international arbitration practitioners.  The growth of the practice has continued in recent years, with the hire into the London office of investment treaty specialist Sarah Vasani from King & Spalding and construction specialist Gerlando Butera from the Singapore office of Nabarro.

Earlier this year, the firm recruited Ronald Sum (former east Asia head of arbitration at Locke Lord) into the Hong Kong office.  Paul Hughes and Jamie Kellick, who are based in the firm's Dubai and Oman offices respectively, were also promoted to the partnership.

Tweedale, Vasani, Sum and Hughes are all currently sitting as arbitrators, as well as pursuing their counsel practices.

Simon Kamstra said "Jon has in the twelve years since he joined us done an enormous amount to help us build the reputation of our practice in the market. Having worked with him so closely and productively over that period I am  personally delighted that he will be working with me to spearhead the further growth of our practice and the talented team of arbitration lawyers we are privileged to lead".
