In Scotland, both Scots and English are spoken, with each being more prominent in different areas.
This is very misleading to foreign audiences who don't know any better.
Overwhelmingly, the language spoken in Scotland is English. While in the 2011 census 1.5 million people claimed to be able to speak Scots (out of a population a little under 5.5 million) in the same census 93% of people reported speaking English exclusively at home; only 1% reported speaking Scots at home, broadly on a par with Polish.
What you're reading in the previous comment is a reflection of the desire by some Scottish nationalists to encourage, promote and overestimate the prevalence of Scots and Gaelic in order to bolster a distinctive Scottish political identity. To be fair, historically the English did exactly the same in reverse - suppressing the teaching of Scots and Gaelic in order to support integration into a single British political identity. Nonetheless, if you are genuinely curious about the facts, English is overwhelmingly the language spoken in Scotland, with Scots and Gaelic spoken rarely, and even more rarely as a first language.
Saying "Both Scots and English are spoken in Scotland, with each being more prominent in different areas" is technically true, but only as much as is the equally misleading statement "Both English and Navaho are spoken in the United States, with each being more prominent in different areas".
