Congress leader Shashi Tharoor was amused to see a man in "swim trunks" show up in a photo of Canadian Prime Minister Justin Trudeau and his family, taken today at the Taj Mahal.

"Great pix but also hilarious that a guy in swim trunks managed to photobomb the Prime Minister!" Tharoor tweeted on Sunday.

Problem: The man in question was Arvind Kejriwal. The Delhi Chief Minister was 'wearing' a towel. And no, he wasn't actually there.

"Apologies. I hadn't noticed it was a photoshopped image. Always dangerous to trust genuine-looking photographs on social media," Tharoor wrote later, in a reply he posted beneath the first tweet.

His original post was a response to pictures shared by the Twitter user @JayasreeVijayan.

Take a look.

Apologies. I hadn't noticed it was a photoshopped image. Always dangerous to trust genuine-looking photographs on social media!! Shashi Tharoor (@ShashiTharoor) February 18, 2018

And other Twitter users had fun.

A half nanga Kejriwal in a pool, photobombing a visiting PM, is genuine looking? Oh @ShashiTharoor !!!! ?? February 18, 2018

This (LLRC) likely means "Laugh Like Renuka Choudhury" The senior Congress leader herself recently noted the emergence of the term, according to an NDTV report.
