UK’s Royal Mail checks all post packages from Bulgaria, the Check Republic and Poland.

The post authorities suspected that post from these countries may contain forbidden substances, drugs, cigarettes or child pornography, a reportage of Czech television Nova said.

As a result, parcel post sent from the Czech Republic to the UK was regularly delayed by 12 days, Nova said as quoted by Bulgarian National Radio (BNR).

A Royal Mail representative said that the measures were introduced after child pornography was found in postal parcels from these three countries.

No official reaction from Bulgaria had followed yet, BNR said.
