The ⁦Royal Opera House has announced the cancelation of various performances due to the tube and national rail strikes.

The company noted that it must cancel “Madama Butterfly” on June 21, the Friends Rehearsal of “Così fan tutte” on June 22, and the performance of “Così fan tutte” on June 25.

The company said, “It is very rare for the Royal Opera House to cancel performances, and we have done everything in our power to try to avoid this outcome. However, due to the sheer numbers of staff and artists unable to travel to and from the building, including essential technical and stage crews, we have been forced to make changes to the schedule which means technical rehearsals essential for the safe running of performances can now not take place. All affected audiences have been contacted. We would like to offer our sincere apologies for any inconvenience caused.”

The Royal Opera House is set to return to performances on June 27 with “Madama Butterfly.”
