Allen & Overy (A&O) is relocating London capital markets partner Stephen Miller to Hong Kong, to lead its Asia capital markets practice.

When he moves in September, Miller will take on the newly created role of regional practice head.

Miller's relocation follows the hire of US-qualified Davis Polk & Wardwell counsel Alex Tao, who has joined the magic circle firm as a partner in Hong Kong.

Former Hong Kong international capital markets head Walker Son left the firm at the end of last year and was replaced in the role by Hong Kong- and UK-qualified capital market partner Yvonne Siew.

When Miller joins its Hong Kong office, A&O will have a total of six capital markets partners in Hong Kong, two of them US qualified. In addition, the firm has six capital markets partners in Singapore, four of whom are US qualified.

Son's departure follows a series of exits by US-qualified lawyers from A&O's Hong Kong office in recent years.

In January last year, A&O capital markets partner David Kuo left to join Milbank Tweed Hadley & McCloy's Hong Kong office.

Kuo joined several US-qualified A&O alumni, including partner Jim Grandolfo, counsel Paul Pery, and associates Kurtis Sherwood and Adam Heyd, who left A&O to join Milbank at the end of 2013.

Recent mandates for A&O's Hong Kong capital markets team include advising on two bond issuances by state-backed Indian companies.

US- and English law-qualified Hong Kong capital markets partner Amit Singh led as Indian power utility company NTPC and export finance institution Export-Import Bank of India issued bonds to raise funds overseas.
