STV News is reporting that Cllr Lisa Beattie (Midlothian East), the SNP leader of Midlothian Council has resigned, just five weeks after taking up the post.
The May election resulted in a balanced council with both Labour and the SNP holding eight seats, in addition to one Independent and one Green.
After Green Cllr Ian Baxter (Bonnyrigg) said he could not keep Labour in power after campaigning for change, the SNP formed a coalition with the lone Independent with Green agreement to abstain on voting for the new council leader.
The reasons for the resignation have not been given, but Deputy Leader Cllr Jim Bryant (Dalkeith, also SNP) has become Acting Leader until a new selection can be held next Tuesday. The SNP will still need their coalition partner to vote with them along with a Green abstention to elect a new council leader.
According to the BBC, Cllr Beattie was forced to resign by her SNP colleagues who threatened a vote of no confidence in her leadership. Read the full BBC article here.
