Ukrainian President Volodymyr Zelensky's decision to replace his defence chief has been seen primarily as an attempt to clean up corruption. But the appointment of Rustem Umerov, a Crimean Tatar and a Muslim, is a signal that Ukraine is serious about returning Crimea, which Russia annexed from Ukraine in 2014.
Speculations about the replacement of Oleksii Reznikov, Ukraine's defence minister since November 2021, have been rife for months.
While personally not accused of any wrongdoing, the man by President Zelensky's side since day one of the Russian full-scale invasion was seen as unable to stop corruption penetrating his ministry.
Military procurement scandals and accusations of bribery against officials at enlistment centres made him damaged goods in the eyes of Ukrainian society, currently in need of a morale boost in the wake of a slower than expected offensive.
