Johann Lamont has resigned as leader of the Scottish Labour Party accusing the Westminster leadership of treating the party in Scotland as a "branch office".
The Queen has been targeted by Twitter trolls after sending her first royal tweet.
The official @BritishMonarchy account she used saw its followers grow by tens of thousands, but was immediately attacked by trolls sending abusive messages.
A Buckingham Palace spokesman said: "We were fully cognisant of the nature of Twitter, where anyone anywhere can express their opinion, but we were delighted that so many people - in their tens of thousands - responded positively.
"We saw some tweets with profanity but that is just the nature of the format."
Scotland Yard said it had not received any complaints and was not investigating the matter.
The number of people killed in the Ebola outbreak has risen to 4,922, the World Health Organization has said.
The WHO said there has been 10,141 cases of Ebola in eight countries so far.
Majority of Ebola victims died in Guinea, Liberia and Sierra Leone, the three West African countries affected the most.
The overall figures include outbreaks in Nigeria and Senegal, deemed by the WHO to be now over, as well as isolated cases in Spain, the United States and a single case in Mali.

Announcing her resignation, Ms Lamont told the Daily Record:
An Iranian woman convicted of killing a man she said tried to rape her has been executed, despite international campaign urging a retrial.
Reyhaneh Jabbari, 26, was arrested in 2007 for the murder of Morteza Abdolali Sarbandi, a former employee of Iran’s Ministry of Intelligence.
She was sentenced to death in 2008 after what Amnesty International called a "deeply flawed investigation and trial".
Miss Jabbari admitted to stabbing the man, but said she acted in self defence after he tried to sexually abuse her.
"Her claims do not appear to have ever been properly investigated," Amnesty International said.
Reyhaneh Jabbari’s execution has been deferred a number of times, including last month.
