Germany's government and its state premiers have agreed to extend social distancing rules until 29 June to contain the coronavirus pandemic, a government spokesman has said.

The deal, confirmed by the spokesman after being revealed to Reuters by a source, follows a dispute over how quickly to ease lockdown measures that have helped Germany weather the outbreak with far fewer deaths than European peers.

Under the agreement, public gatherings of up to ten people would also be allowed from 6 June, the government spokesman said.

Chancellor Angela Merkel originally suggested extending the distancing rules, which require people to stay 1.5 metres apart, until 5 July, as the conservative leader is worried about a second wave of cases that could require another costly lockdown.

The country's 16 states have been hit to differing degrees by the coronavirus, and Thuringia in the east, which has had fewer cases, voiced its dissent in separate statement.

Germany has seen 8,302 deaths from the coronavirus - far fewer than in Italy, Spain, France or Britain - and an initial easing of the measures does not appear to have caused amajor spike in cases.

A government source said the cabinet may also decide to lift a warning against travel to 26 fellow EU countries plus Britain, Iceland, Norway, Switzerland and Liechtenstein from 15 June,opening the way to separate advice for specific regions.

Markus Soeder, premier of Bavaria, the hardest-hit state,voiced opposition to moving too fast in reopening tourism.

"We have in Italy, Spain and France completely different infection numbers compared to Germany so I ask the federal government to think very carefully about this," he said.

"Nobody should be fooled. Corona remains deadly," Mr Soeder said, describing Thuringia state's shift towards adopting voluntary, localised measures as a "fatal signal".

In a nod to Bavaria's objections, the cabinet might postpone its decision by a week, but still lift the blanket travel warning from mid-June, media group RND reported.
