Across the block, the average contraction was 11.9%.
Mr Henkel, who resigned from the European Parliament last year, told Express.co.uk: “The eurozone shows perfectly why it is foolish to change economies to adopt a common currency.
“On the contrary, a currency should rather correspond to the reality of a country’s economy.
“In other words: it was wise for Britain to keep the pound and it was foolish for Germany to give up its D-Mark. ”

“However, even before the corona crisis, the eurozone was seriously lagging behind not only the world but also EU countries that are not part of the eurozone.
“No wonder countries like Denmark, the Czech Republic, Sweden and Poland have no desire to join the common currency.
“This currency” one size fits all “is actually only suitable for France.
“It is too low for Germany and the other northern countries; it is too strong for the southern euro-zone countries.
“Result? Italy, Spain and Greece lost their export markets as Germany’s trade balance exploded! ”
Mr Henkel added: “The euro is like a shirt that is only available in one size.
“For some it’s too tight, for others it’s way too wide.
“As a result, countries like Italy or Spain have to lose weight to adapt, that is, need a lot of reform, while Germany’s productivity has to drop, which ‘she has been doing for years.
“The euro is however perfectly suited to France; one of the reasons why this country remains reluctant and unable to reform.
“If the euro is to survive, it can only do so by becoming everyone like the French. “
