Good morning. Melbourne is in lockdown, China and the US are at odds, and there’s more tension between the UK and the EU – it’s Groundhog Day Friday 28 May, and this is Imogen Dewey with the main stories to see out your week.

Victorians are waking up in lockdown (again) after the government opted for tough measures to contain a growing Melbourne-based Covid-19 cluster. For those in the state, here’s a list of the latest rules and exposure sites. Amid mounting concern this wave could have become “uncontrollable”, the Morrison government is under attack over “failed” quarantine arrangements and the sluggish pace of the national vaccine rollout. Families of residents at an unvaccinated Melbourne aged care home were “flabbergasted” by comments from the aged care minister, Richard Colbeck, who claimed earlier yesterday that those not yet vaccinated had “chosen not to take the jab”. And Victoria’s vaccine hotline crashed for hours, inundated with calls after the state government’s decision to open up vaccinations to those aged over 40 (announced with the lockdown).
