"I am used to taking responsibility and I can definitely say I'm not going to become the premiere in order to fail and ruin the undertaking," he said, answering the question whether his premiership ends similar to PM Yatsenyuk’s one.
Speaker noted that if he seeks to reform a sector as prime minister, for instance, customs, then he will complete it without anyone’s permission.
"One more thing for you to remember, I will ask no one for any permission. If my views are required to change the situation at the customs office, I will implement it. It’s better to block me today, prevent me from doing it by all means - but I'll finish it anyway," said Groysman.
