On April 6 Lukashenka accepted resignation of Interior Minister Uladzimier Navumau.
The formal explication of the resignation is not credible. Uladzimier Navumau recently showed an excellent physical condition.
It is unlikely that the cause of resignation was the letter of anonymous employees of law-enforcement bodies critical towards Navumau which had been recently circulated on Internet.
Also there are grounds to doubt other possible causes of resignation which are being put forward by some observers.
