The flag colours -- red, gold and green-- was turned upside-down to green, gold and red.

In a pointed tweet, the NDC said: "That the Ghana flag is turned upside down is yet another manifestation of the chaos in government."

Others accused the party of engaging in trivialities.

The flag gaffe was first flagged by Ghana's former Foreign Minister, Hanna Tetteh.

She tweeted: "Protocol must have been distracted. I hope next time our flag is turned right."
