British government threatens to ban all outdoor exercise

19:50 The German Economic Institute (IW) has come up with a 12-point planto lift movement restrictions in Germany, once the coronavirus outbreak is under control. The newspaper Bild reports that the plan calls for medical capabilities and testing to be boosted. Then schools and kindergartens could reopen and public transport ramped up, allowing public institutions to return to normal initially. Restaurants and stores could then reopen, possibly under orders to allow patrons to maintain a safe distance. Later, the private sector could restart their businesses and borders with the rest of the EU can be reopened. The other stages of the plan include the loosening of rules for paying taxes and debt and allowing migrant labor to return safely. Finally, the government would need to cut taxes, boost domestic demand, and launch a new program of economic stimulus, according to the IW report.
