There are 8 council by elections on the 1st October 7 of them in Scotland of which 4 were because the SNP counciller is now the MP for the area having defeated the Labour MP. So far the SNP has swept all before them continuing on from the great General Election result they had. Can Corbyn or his new Scottish Labour leader change this?

The first 25 local council by-election seats in Scotland since the 2015 General Election
