Why is Poland allowing this person to be in the country, while it is officially friendly with the current Kiev regime?
Answer is simple. Saakashvili works for specific USA and western European circles and, official Poland, being obedient, accepting everything that coming from those circles, this creature included.
Perhaps it is a signal of displeasure intended for Kiev.
No. It can be understand this way or another. It can appear whatever we imagine but, only as the collateral effect. Primary reason is as I said in previous quote- to satisfy some people who dictate politics of official Poland (of previous Polish government and new one).
You want to found what political force in Poland tries to focus on Poland`s and Polish interests? Search for that force among any political party and movement that suggest good relations with Hungary and Serbia.
Prominent Ukrainian opposition politicians and EU parliamentarians have agreed to escort Saakashvilli through the border crossing.
See, that is that link. Servants of those specific circles helping to creature.
