Economic forecasts grew darker today as industry output in both Germany and France, the eurozone's two largest economies, showed more signs of weakness.
In France, the ongoing uncertainty caused by Macron's snap election has been amplified by evidence the economy is "stalling".
Both service and manufacturing activity fell in June, according to flash PMI data from S&P Global.
Norman Liebke, economist at Hamburg Commercial Bank, said: “The uncertainty of the upcoming elections has French businesses stalling and fearing tougher times.”
The PMI index dropped to 48.8 in June, down from 49.3 in May below the all-important 50 mark, which marks the difference between contraction and growth.
In Germany, while output remained in growth territory it slowed to "a marginal pace" as manufacturing slowed.
Cyrus de la Rubia, chief economist at Hamburg Commercial Bank, said: "After showing some promising signs of bouncing back, the manufacturing sector hit a wall and started moving in the opposite direction in June.
"The production slump is pretty sobering, but what’s even more concerning is that new orders are plummeting at a much faster rate."
