A slip of the tongue by Boris Johnson.
Boris Johnson: 01 we’ve had very very powerful denunciation of Russia 02 and my poleague er colleague 03 Jacek Czaputowicz 04 er in on Friday in London
In line 02, it is not clear why Johnson said ‘poleague’ instead of ‘colleague’ but it may have been due to the fact that Jacek Czaputowicz is the Polish Foreign Minister. The first syllable of ‘Polish’ /po-/ replaces the intended target /co-/ to create a word blend (polish + colleague).
Classification: Word blend
