BRUSSELS (Reuters) - European Council President Charles Michel postponed a summit of the bloc’s leaders due this Thursday and Friday to Oct. 1-2 as he went into coronavirus quarantine after being in contact last week with someone who tested positive for COVID-19, his spokesman said. The spokesman also said Michel himself tested negative for COVID-19 on Monday but was following the rules in Belgium, the seat of EU institutions where the summits of EU leaders take place, in going into isolation.
