Brecon Beacons National Park
Name: Brecon Beacons National Park Bannau Brycheiniog National Park

Reasoning: New common name

Policy: WP:NAMECHANGES

Result:

Status:

Note: the previous RM and the reverted move was done soon after the name change was announced so immediately failed assuming it was based on WP:OFFICIALNAMES rather than any chance of WP:NAMECHANGES and WP:COMMONNAME.

Technically this could just be renamed Bannau Brycheiniog, omitting "National Park". This is because 1) only the national park adopted the name, it is not automatic for the mountain range to be called such, and there are few new sources on the range to determine whether a new name is used. 2) Most readers when they would've heard "Brecon Beacons" and now "Bannau Brycheiniog" are more likely to reference the national park, so even if somewhat named after the range, the national park is more likely the WP:PRIMARYTOPIC under either name.
