Pubs, restaurants, offices and public transport are all covered by the ban
A village on the border between England and Wales has been split by a ban on smoking in enclosed public places.
The ban came into force across Wales on Monday morning but parts of Llanymynech are in Shropshire.
One landlord on the Welsh side, Chris Haddon, from the Dolphin, described it "very unfair" as some other pubs remain unaffected until July.
"I'm in a sort of position where I could lose my business. It's as simple as that," he said.
"I do think it was very, very unfair that they brought it in right on the border.
"It should've been Scotland, England, Wales all (on) the same day - done, dusted and then it's fair competition."
Pubs, restaurants, offices and public transport are all covered by the ban in Wales, which came into force at 0600 BST.
Those found smoking can face on-the-spot fines of £50, while those in charge of premises could also be fined for allowing smoking.
A similar ban is already in force in Scotland. Northern Ireland will follow suit on 30 April and England on 1 July.
