No fewer than 16 of the SNP's 55 MPs are boosting their £74,000 salaries by renting out property, according to Parliament records.

Westminster's Register of Members' Financial Interests shows several of the party's new MPs let multiple properties.

Lisa Cameron, the MP for East Kilbride, Strathaven and Lesmahagow, receives rent from a house in Lanarkshire and five flats in Edinburgh and South Lanarkshire.

Tasmina Ahmed-Sheikh, the Ochil and South Perthshire MP, rents out three flats in Glasgow and a house in Kingussie.

A third MP, Ian Blackford, who represents Ross, Skye and Lochaber, owns two cottages on Skye, the rents from which are paid to First Seer, his holiday croft business.

Under Commons rules, MPs must register properties they own worth over £100,000 or which earn a rental income of £10,000 per year.

They do not have to register property which is used as their own, or their children's home.

Among the others, Richard Arkless, the MP for Dumfries and Galloway, rents out a house in Broxburn and a flat in Glasgow.

Angus MacNeil, who was re-elected MP for the Western Isles in May, jointly owns a rental house in Fort William and also owns and rents out a flat in Glasgow and one in London.

Patricia Gibson, Steven Paterson, John Nicolson, Chris Law, Deirdre Brock, Calum Kerr, Tommy Sheppard, Martyn Day and Stuart McDonald have also registered property interests. with the Westminster authorities.

John McNally, the Falkirk MP, collects £600 per month from a hair dressing salon he owns in Denny.

In addition to property, several have outside business interests, including Dundee West MP Mr Law, who is a director and significant shareholder in CMAL Ltd, a financial services company.

Alex Salmond, the former First Minister, earns £108,000 per year from writing newspaper columns, according to the Commons register.

Under SNP rules, the party's MPs are expected to treat their Commons job as a 'full-time commitment'.

Senior Nationalists have in the past criticised Conservative and Labour MPs who held second jobs or directorships.

SNP MPs were urged not take a recent £7000 pay rise which took their basic pay to £74,000.

Angus Robertson, the SNP's Westminster leader, said the money should go to good causes.

According to the House of Commons Register of Members’ Interests, 16 SNP MPs list property interests from which most receive rental income.

Under the rules, they are required to list a property if (i) its value is over £100,000 and (ii) if they receive rental income of at least £10,000 a year.
