Southeast English are autosomally closer to the Welsh and Scots than to the Flemish/Belgians*, they are even closer to the Irish than to the Belgians. The Flemish/Belgians are really not that close the English, unlike the South/Central Dutch, I don't where the idea came from that they are. Probably anthrotardism, like most opinions here.

*by IBD/Fst the English are closer to Belgians (hence the England & NW Europe category on AncestryDNA), as well as Germans, Northern French and Danes than they are to Insular Celts, which goes to show that those genetic measures are less reflective of phenotypical differences.
