From the Google Translation of the letter, the President of the Polish federation has not been on good terms with Hein or Pat:
I've never been judged by the Ethics Committee UCI. Both myself and the then President Vladimir Holecek UEC, we were interrogated by the Commission at the request of Hein Verbruggen, who wanted to scold us but also the whole of Europe. To date, there is no judgment declaring me guilty of violating the Code of Ethics UCI, as the Ethics Committee found no basis to formulate a sentence.
The difference between you and Igor Makarov is that he gives money to the development of cycling and you takes them for their work. Ouch! A veiled accusation that Pat is skimming.
There you will present his plan to the global ("not British, not Irish, not Russian"). This comment suggests he's getting caught up on the same old criticism that he doesn't think about cycling promotion on a global scale.
Based on my recollection of the UCI's rules, Makarov has a vote because he leads the aggregation of all European cycling federations. Historic evidence translated to English suggests Makarov is not treated well inside the UCI.
