David Pemsel, chief commercial officer of Guardian publisher Guardian News & Media, has been promoted to deputy chief executive.

Pemsel, the former ITV marketing director, will take over responsibility for GNM's commercial operations in the UK, US and Australia. He will continue to report to Andrew Miller, chief executive of GNM parent Guardian Media Group.

Tony Danker has also been promoted, to GNM director, international and partnerships, leading further international expansion.

Danker currently oversees GNM's international, rights and syndication operations and played a key role in the launch of Guardian Australia earlier this year.

Michael Bloom, chief executive of Guardian US, is leaving the company at the end of January. Bloom joined GNM in late 2012 and previously worked in senior digital roles at Rolling Stone/Wenner Media, MTV Networks and AOL.

Miller said: "In order to capitalise on the momentum we have created, now is the right time to integrate our commercial operations across the UK, US and Australia in line with our global strategy and ambitions."
