KIEV - Ukrainian Defense Minister Oleksii Reznikov said on Monday that he has submitted a letter of resignation to parliament chairman Ruslan Stefanchuk.

It was an honor to serve the Ukrainian people and work for the Ukrainian army for the last 22 months, the toughest period of Ukraine's modern history.

In the letter, Reznikov, who was appointed as defense minister in November 2021, said that all the key tasks set for his mandate have been accomplished.

On Sunday, Ukrainian President Volodymyr Zelensky said that he plans to dismiss Reznikov and ask parliament this week to confirm Rustem Umerov, head of the country's main privatization fund, as his replacement.

The parliament is set to vote on the appointment later this week
