Former Prime Minister Sir John Major has warned a minority Labour government propped up by SNP votes would be a "recipe for mayhem".
In a speech in the Midlands today, Sir John said it would lead to a "weak and unstable" administration which would wreck Britain's economic recovery.
Sir John Major said that Nicola Sturgeon talking about the SNP changing the policy of the government delegitimises a Labour coalition - as she is not a candidate for the House of Commons.
The former Prime Minister was answering a question from ITV News Correspondent James Mates:
SNP leader Nicola Sturgeon could present a potentially long-term problem for Labour.
Sir John will give a speech later today saying a Labour-SNP government would be "weak and unstable" and wreck Britain's economic recovery.
