DUBAI (Reuters) - Saudi Arabia is planning a multi-billion-dollar share sale in energy giant Aramco as soon as June in what would be one of the region's biggest stock deals, two people familiar with the matter said.

The offering could raise around $10 billion, one of the people said. The preparations are ongoing and the details could still change, the sources said, who were speaking on condition of anonymity because the matter is private.

The shares will be listed in Riyadh and it will be a fully marketed offering rather than an accelerated sale over a few days, they added. The government's communication office and Aramco did not immediately respond to a request for comment.
