Cards are reactivated once repayments are made and disputes resolved

Biggest deficit was run up by Ian Paisley who owed £27,000 to IPSA

More than a dozen MPs including the SNP Westminster leader Angus Robertson, suspended Labour MP Simon Danczuk and ex-minister Liam Byrne have had their Commons credit cards blocked.

Parliament's expenses watchdog suspended the cards after debts of up to £27,000 were run up between June 30 last year and February 23.

IPSA reactivates the cards once wrong claims are repaid or disputes are resolved.

Five SNP politicians were among the 14 who were sanctioned by the Independent Parliamentary Standards authority. Four of the party's representatives have since repaid sums ranging from £33 to £3,446 in full.

Natalie McGarry, who has been suspended from the SNP amid allegations relating to missing donations, owed £2,270 when her card was blocked on January 25, according to the figures released to the Press Association under Freedom of Information rules.

She had £2,370 outstanding as of February 23. Her office blamed a 'mix up' and said the situation had now been 'rectified'.

Democratic Unionist Party (DUP) MP Ian Paisley was £27,766 in the red when his card was stopped last November, and the deficit was £20,337 by last month.

Shadow work and pensions secretary Owen Smith, former minister Liam Byrne and backbencher Simon Danczuk are on the list, having owed £953, £1,189 and £595 respectively. The amounts have all since been cleared.

Labour ex-policy chief Jon Cruddas was subject to action before Christmas over £2,967 of expenses.

Mr Cruddas said he exceeded the printing and postage budget for last year and had now agreed to settle the overspend by April 1.

Tory backbencher John Stevenson had his card blocked in December over £608 of debt, but has since settled the amount.

Fellow Conservative David Morris's card was suspended the same month, when he owed £12,240. He said Ipsa had initially failed to process the transactions properly and later discovered an overspend in office costs of nearly £5,000.

'This overspend happened due to numerous admitted errors by Ipsa with their system, but under the scheme any budget overspends must be personally reimbursed by the member from their own pocket,' he said.

'This issue has now been resolved and the amount agreed as owed is being paid back by myself from my own pocket.

'I must stress that these expenses claimed for were all permissible claims and were legitimate office costs incurred by carrying out my parliamentary duties to my constituents.'

Natalie McGarry, who was suspended from the SNP over a missing donations row, still owed £2,370 on February 23. Liam Byrne has repaid £1,189 after his card was suspended.

Ms McGarry's office said her card was currently operational. 'There was a mix up in the payment of the deposit for accommodation, but this has since been rectified, and Ipsa are satisfied with the repayment,' a spokeswoman said.

Ipsa issues MPs with credit cards to pay for a variety of items such as travel, accommodation and stationery.

The politicians then have to prove the spending was allowable within a month, or they build up debts to the watchdog.

The sums are recouped by suspending the cards and not paying out valid expenses claims, or in instalments from the MP's salary.

The latest details date from the end of June, when a previous disclosure sparked a furious row between Work and Pensions Secretary Iain Duncan Smith and Ipsa about whether his card had been suspended over a £1,000 debt.

Some of the new cases involved disputed claims, with energy select committee chairman Angus MacNeil building up a £950 tab after charging a series of hotel bills for more than £250 a night. He insisted the rooms were the cheapest available, but has now repaid the difference above Ipsa's £150-a-night maximum rate.

Angela Crawley is the only SNP MP listed as having had her card suspended and still being in debt as of last month, owing £2,152.

An SNP spokesman said: 'By its very nature the operation of the expenses system means that Ipsa often owes outstanding amounts to MPs and MPs often owe outstanding amounts to Ipsa. Outstanding amounts are then repaid.'

The watchdog was challenged about the credit card rules by SNP MP Pete Wishart at a hearing of the Speaker's Committee that oversees it this week.

Mr Wishart complained that having to provide evidence for spending within a month could be 'burdensome' and highlighted that new SNP MPs had seen their cards suspended.

'Ipsa had made such a fantastic impression on our new groups of MPs when they were newly elected,' he said.

'There was goodwill towards Ipsa. Totally gone after that.'

But the watchdog's chief executive Marcial Boo responded: 'I am obviously very sorry that it has cost a lot of goodwill. But it is part of the role that we have to make sure that payments that we make are supported by evidence.

'As soon as MPs provide us with that evidence the card is turned back on again.'

He added: 'We cannot allow ourselves to be in a position where an MP is making thousands of pounds of payments on a card and failing to give us evidence to support that payment, without taking any action.'

Mr Byrne said he was appealing after Ipsa refused to pay for leaflets to let constituents know about surgeries and other events.

'Ipsa is disputing whether they should pay for the invitations to residents' meetings and leaflets with information about my surgeries,' he said.

Labour front bencher Owen Smith has repaid £953, while SNP Treasury spokesman Stewart Hosie repaid £3,446 after his card was suspended

'But I think this is a point of principle. So, having discussed it with Ipsa's chief executive, I'm taking it to tribunal.

'Ipsa does a really difficult and important job and I will always defend it.

'But, MPs need to be at the service of their constituents - and that means residents must know how to get hold of the people they elect.'

Plaid Cymru MP Hywel Williams had his card suspended over £2,183 of debt in November. He blamed Ipsa's 'incompetence' for the issue, saying the watchdog continued paying the rent on a flat for two months after he moved out.

Mr Williams said he was later told to ask his old landlord to repay the money. 'She repaid one month and asked for a receipt before paying the rest,' he said. 'Ipsa failed to do this despite repeated requests.

'Eventually Ipsa withdrew my parliamentary credit card, whilst I was trying to pay for parking and buy a train ticket - and catch the train - this without warning me.

'In the end they provided a receipt. She paid off the outstanding amount. They then reinstated my card.

The SNP confirmed that all the card suspensions had now been lifted.
