PM Modi has often been targeted over his humble "tea seller" background, which he invariably used as a stick to beat his rivals with.
"Berozgar yuvao ko pakode ka thela lagane ka sujav ek chaiwala hi de sakta hai. Arthshastri aise sujav nahi deta!!!," (Only a tea seller can suggest to unemployed youth to sell snacks, an economist would not do that)," Mr Patel said in a tweet today.
The Patel quota demand spearhead was apparently comparing PM Modi to former prime minister Manmohan Singh, an eminent economist.
Mr Patel had backed the Congress in the recent Gujarat Assembly elections.
In the run up to Gujarat elections, the Congress's youth wing mouthpiece, 'Yuva Desh', had tweeted a meme on the teaseller background of PM Modi.
It showed PM Modi, US President Donald Trump and UK Prime Minister Theresa May in one frame. Prime Minister Modi was shown mispronouncing the word 'meme' as 'main main', prompting President Trump to correct him. May was shown telling PM Modi: "You go, sell tea".
Congress leader Mani Shankar Aiyar had, in the run up to the 2014 parliament elections, spoken about PM Modi's 'chaiwala' background. The prime minister had used it to turn the tables on the Congress, accusing it of disdain for the poor.
