Shmyhal is predicted to be the main candidate for the head of the OP

The most likely candidate is the current Defence Minister Shmyhal

No final decision on the appointment of the new head of the Presidential Office as of today no. This was reported by the sources of the US publication.

Who can head the OP

According to preliminary data, the most likely candidates for the position of the head of the OP are current Minister of Defence Denys Shmyhal.
If he is appointed, the Ministry of Defence may head Mikhail Fedorov, who is now head of the Ministry of Digital Transformation.

Why this particular configuration

Sources note that Fedorov is close to Drapatyi (probably to the leadership of the security forces), which should simplify the coordination of the defence sector.

It is also noted that the change of the Commander-in-Chief of the Armed Forces of Ukraine Oleksandr Syrskyi has been brewing for a long time, and a possible rotation in the OP could be part of a broader personnel renewal in the security and defence sector.

Context.

Following the resignation of Andriy Yermak, Ukrainian politics has been actively debating the future architecture of the country's command and control and approaches to defence planning in a protracted war.
