[custom_adv] A Thai activist who claims to have been sent pictures of the King's mistress has shared some of the photos with MailOnline. News of the 1,400 leaked images made headlines this week as the pictures laid bare infighting between King Vajiralongkorn's wife, Queen Suditha, and his harem of mistresses. [custom_adv] Photos sent to this publication are said to show the billionaire monarch's 'royal noble consort' Sineenat Wongvajirapakdi, who has returned to the royal fold after she was dramatically expelled and jailed last year. [custom_adv] Pavin Chachavalpongpun, a prominent royal critic based in Japan, told MailOnline he was anonymously sent the images on an SD card in August along with a letter claiming they were hacked from Sineenat's phone while she was in prison. [custom_adv] Suspecting they were sent by Sineenat's rivals, possibly allies of the King's official wife Queen Suthida trying to 'sabotage' her return to the royal court, Pavin says he has shared some of the photos in order to 'show the other side of the monarchy'. [custom_adv] Some of the images purport to show the consort completely without clothing, but Pavin has chosen not to publish these photos. Several of the photos show her baring her unshaven armpits - though it is not clear why. The same photos, apparently taken between 2012 and 2014, were also sent to other royal critics outside Thailand. [custom_adv] Pavin said he received the anonymous envelope in late August, postmarked in France and containing an SD card on which the photos were stored. Almost all of the photos were selfies, he said, some of them taken in a bathroom or in her car - with some of them showing the subject without clothing and showing 'every single thing that you could imagine'.
