Last modified on Mon 5 Apr 2021 10.44 EDT French prosecutors have opened an investigation into claims government ministers and other wealthy guests attended secret Paris dinners that broke Covid rules. The scandal emerged after the television channel M6 broadcast hidden camera footage allegedly from a high-end restaurant where diners were shown enjoying caviar and champagne as part of gastronomic menus costing up to €490. The address was known only to a “privileged few”, M6 claimed. The film showed diners failing to maintain recommendedCovid rules including not socially distancing, not wearing masks and some greeting each other with bises (kisses on the cheek). Staff were also shown without masks.
