LABOUR'S election co-ordinator Douglas Alexander has said Ukip could hurt the party's chances in 2015 - and compared the impact to that of the SNP.
Many Labour MPs are concerned about the inroads Ukip is making into some Labour-held seats.
In previous elections the party has considered Ukip a threat to the Conservatives.
But opinion polls now suggest Ukip is now taking support from Labour
Mr Alexander said:"After 30 years in the Labour party in Scotland where we saw a populist party of the right start by taking out Tory MPs and later take out Labour MSPs I can assure you I am the last person that needs to be convinced about the threat posed by Ukip, not just to Labour but to all political parties in the UK."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
