The Ministry of Defence (MOD) has appointed its first Welsh Language Champion.
Welsh-speaking Air Commodore Adrian Williams, the RAF's most senior officer in Wales, has been appointed to the role with the approval of the Welsh Language Commissioner.
Air Cdre Williams' appointment is part of an update to the MOD's Welsh Language Scheme, which will also see additional guidance on how to strengthen engagement and interaction with the Welsh-speaking public across defence.
Air Cdre Williams said it was "a great privilege" to take on the role.
"As someone who was brought up in a Welsh-speaking household, and who went to a Welsh-speaking school, I have always been passionate about our native language and understand its central importance to people and communities across Wales," he said.
Air Cdre Williams will take on his new duties alongside his existing role as Air Officer Wales.
He will enhance defence's ability to operate bi-lingually in Wales while championing the Welsh language in the sector, the MOD said.
"The publication of MOD's updated Welsh Language Scheme signifies our commitment to further strengthen our abilities to operate bilingually in Wales and I very much look forward to leading this work," he said.
The scheme recognises the pledge to significantly increase the information available on the Welsh-English portal of the Government's website and the updates will also see an increase in Welsh language social media posts through UK defence's official accounts.
