The big question is wether or not the UK will have a simmilar agreement to Switzerland regarding import and export of plants. even though not in the EU, it has an agreement that means that it is as if though it is in the EU when it comes to sending and recieving plants from eu countries. This is why no phyto is needed to get plants into switzerland from the UK for example, or from Framce. Neither do plants need a phyto from Switzerland to enter the UK or France...but indeed..who knows what wilé happen soon...
