That's what Amīlija Raituma, a KNAB representative, told Latvian Radio August 31.
She told Latvian Radio that there are indications that part of Memory Water advertisements can be considered to be hidden campaigns.
"Third parties can do [political campaigns] as well, but it can't be worth over €6,540," she said.
People on Twitter in particular have pointed out that some Memory Water advertisements contain the words "We should begin with ourselves!", which isn't a far cry away from slogans of the KPV LV party.
One Memory Water advertisement even repeats a KPV LV slogan verbatim (the 5:30 mark).
