Miriam Gonzalez Durantez hit the campaign trail in Scotland yesterday to urge voters to reject the prospect of such deals by backing the Liberal Democrats.
She teamed up with UK business minister Jo Swinson to launch a new plan aimed at improving opportunities for women.
As she did so, Ms Gonzalez Durantez revealed she was very proud of what her husband had achieved as Deputy Prime Minister – but insisted he would have done even better if he had held the top job in British politics.
With just over a week to go till the General Election, the Liberal Democrats are facing the prospect of heavy losses in Scotland, where surging support for the SNP has seen Nicola Sturgeon’s party tipped to become the third largest at Westminster.
But both Ms Gonzalez Durantez and Ms Swinson spoke out about the risks of the UK having a Labour administration propped up by the SNP.
