Brussels            -        Tempers flared as the deadlocked EU coronavirus summit rolled over from Sunday into Monday, with French President Emmanuel Macron upbraiding his Dutch and Austrian colleagues and threatening a walk-out.

Frustration had been building for three days as the 27 leaders wrangled over the size and form of an up to €750-billion ($860-billion) package of loans and grants to lift virus-ravaged countries out of recession.

An alliance of so-called “frugals”, led by Prime Minister Mark Rutte of the Netherlands and Chancellor Sebastian Kurz of Austria, has been resisting calls for the bulk of the funds to be doled out as non-repayable grants.

Macron, according to witnesses, bashed the table, attacked Kurz for leaving the room to make a call and accused Rutte of behaving like former British premier David Cameron -- whose strategy “ended badly”.

Cameron often took a hard line at EU summits seeking concessions for Britain, but ended up losing a Brexit referendum -- and his job.

According to a European source Kurz was offended by Macron’s behaviour.

A member of the French delegation told AFP that some of the accounts of what had happened has been “a little caricatured” but confirmed that Macron had “taken a hard line on their inconsistencies”.

According to officials, Macron had denounced the two leaders for their insistence that the recovery funds take the form of loans with strict conditions attached, rather than as grants -- and had said he would rather walk away than make a bad deal.

France wants at least €400 billion to be available as grants, but the Frugals want to cut that back substantially.
