The full BBC Radio nan Gàidheal (Gaelic radio) interview with Dr Donald Boyd, the leader of the Scottish Christian Party, can be heard by clicking on this link. It was only partially broadcast on 19th May 2017.
Dr Boyd was asked about the SCP vision for Inverness and the Highlands, and he was asked in conclusion what the SCP would do to promote the Gaelic language.
He pointed out that Gaelic road signs are unnecessary but of much more use would be to teach school children the meaning of the Gaelic names of the mountains on Highland maps, helping them to understand the geography of the Highlands and to increase interest in one of the main features of the Highlands.
He repeated his 2015 claim that the Scottish National Party has no specifically Scottish vision for Scotland and the Highlands, and this is the reason for voting for the Scottish Christian Party instead.
