Just a few minutes after the attack, Macron's ally, Prime Minister Jean Castex, took the floor of the National Assembly where he warned of attacks on 'the foundations of democracy'. "Respect for the institutions of the Republic and its representatives is a cardinal principle of our democratic life".
While slapping the president, he could be heard shouting "Montjoie Saint Denis", which was the battle cry of the French armies when the country was still a monarchy.
It is not the first time that Mr Macron has been attacked by angry crowd members while out in public.
Politicians from across the political spectrum condemned the physical attack and denounced a political context of mounting verbal violence.
The centrist is widely expected to seek re-election in next year's presidential elections and polls show him with a narrow lead over far-right leader Marine Le Pen.
Macron conducted another tour billed as a listening exercise in 2019 in the aftermath of those protests, which shook the country and saw him promise to change his way of governing.
