The ex-head of state warned that cutting back on the country’s wealth tax would “help the rich get richer while they sleep,” and criticised the government’s attempt to “introduce a lower tax regime for the rich and a higher one for the more modest and middle classes”.
However Hollande was in turn attacked by France’s conservative prime minister Edouard Philippe who demanded he “show some humility”.

“I’m not just talking about the former president. I’m also talking about former ministers, including (former finance minister) Michel Sapin and (former budget minister) Christian Eckert, who think they have the right to reprimand their successors, but yet refuse to own up to their past mistakes.”
Mr Macron earlier brushed off opponents’ criticisms that his economic policies favour the rich, adding that scrapping the controversial wealth tax championed by Mr Hollande would encourage the wealthy to stay in France and invest.
