Tharoor said in a Twitter remark that he posted along with the photograph of the prime minister receiving salute with an army jawan: "A bit taken aback to see a PM taking the salute wearing a party symbol. I beg @PMOIndia not to politicise the Army."
The post, which was retweeted 240 times and favourited 146 times at the time of writing this report, also drew ire from a number of people.
One of the replies to Tharoor's tweet said: "By that Logic, the hand should not be used for salutes, as it also denotes a party of 44 symbol".
Another reply to the Thiruvananthapuram MP read: "And your wife died when you politicised ur personal along with ISIsation & adulteration of the same. Pathetic!"
"...your party has been at the forefront calling Modi a BJP PM and not India's PM. Just a reminder," read another.
There were also a couple of tweets supporting Tharoor's observation but they were clearly outnumbered.
