Scotland's First Minister Nicola Sturgeon says voters across the United Kingdom may need to "get used" to Irish-style multi-party governments. The SNP leader made the comments to Newstalk on a campaign stop in the coastal resort of Largs, as she continued her helicopter tour of Scotland ahead of polling day on Thursday.

Sturgeon, dubbed "Britain's Most Dangerous Woman" by the Daily Mail, has led her party to the brink of a landslide as it seeks to win a strong majority of Scotland's 59 Westminster seats.

"If no party wins a majority on the day on polling day, the reality is they have to work with other parties. We're used to that in Scotland, you're used to that in Ireland. Maybe they'll be used to it across the UK before too long," she said.

It is likely that any Labour minority government looking to unseat the Conservative party would need the support of the SNP to prevent David Cameron returning to 10 Downing Street.

However, tensions between Labour and the Scottish nationalists spilled over yesterday after a rally held by the party in Glasgow city centre was marred by scuffles.

Supporters of Scottish Labour leader Jim Murphy accused the SNP of faciliating a counter-demonstration, which saw abuse thrown at Mr Murphy and comedian Eddie Izzard.

Nicola Sturgeon said the conduct of those who took part in the protest was "disgraceful" had "nothing to do with the SNP".
