From the Telegraph just now:
“Mr Blackford faced further criticism after a leaked recording of an SNP group meeting emerged in which he urged his colleagues to "rally around" Patrick Grady.
Mr Grady, the SNP's former chief whip, was found guilty by the Commons authorities of sexually harassing a young member of staff.
Earlier this month it was reported that Mr Flynn had the required backing to oust Mr Blackford and had told Ian McCann, the party’s compliance officer, that he would put his name forward at the AGM.
'Anyone but Blackford'
One source said that "a lot" of SNP MPs "would be happy with "ABB: Anyone But Blackford."
It is understood that party headquarters persuaded Mr Flynn to back down, shortly before the leader was due to appear on the BBC's Question Time programme.
Joanna Cherry, the SNP's Edinburgh South West MP, welcomed Mr Blackford's resignation, saying: "I’m pleased to hear this. It’s time for fresh leadership & tolerance of debate & diverse viewpoints.
"I hope the SNP Westminster group will be now be left to choose our new leader without outside interference & in accordance with our standing orders."
'Total humiliation for Nicola Sturgeon'
Craig Hoy, the Scottish Tory chairman, said: "Ian Blackford has jumped before he was pushed. His resignation is a total humiliation for Nicola Sturgeon.
"She shamefully stood by her Westminster leader earlier this year despite his appalling handling of the complaints made against Patrick Grady.
"This showed a total lack of judgement by Nicola Sturgeon.”
Gossip if that he’s jumped before he was pushed.
Let’s see what unfolds in the next few days.
