Business Secretary Vince Cable has urged shareholders in British banks to take action on the boards and executives responsible for the "systemic abuse" committed during Barclays rate-rigging scandal
He said that nobody at Barclays was prepared to take responsibility for the rate-rigging revelations that have engulfed the company in recent days and that shareholders should "get a stronger grip" on the boards.
Mr Cable's comments came as Bob Diamond, the bank's embattled chief executive, prepares to face a panel of MPs over the controversy on Wednesday.

Ministers have also announced an independent review into the inter-bank lending rate in the wake of revelations that it was rigged by Barclays and other financial institutions.
Writing in an article for The Observer, Mr Cable said: "Regulators are a backstop: they don't own banks.
"The governance at the top of our leading banks has been shown to be lamentably weak. No one at the top of Barclays will take responsibility for systemic abuse."
He added: "Shareholders, the owners, have a major responsibility here. I am bringing in legislation to strengthen their control over pay and bonuses, through binding votes, but shareholders have to get a stronger grip on weak boards and out-of-control executives."
Mr Diamond is facing growing demands for his resignation in the wake of the scandal and there appeared to be moves by investors against the bank's chairman, Marcus Agius.

The government said the independent review will consider the future operation of the so-called Libor rate and the possibility of introducing criminal sanctions for its manipulation.
The move did not satisfy Labour, however, whose leader Ed Miliband insisted the public would not accept anything less than a full-scale independent inquiry into the culture and practices of banking.
bility of introducing criminal sanctions for its manipulation.
MIliband has called for a 'full public inquiry'
His call came after the Financial Services Authority uncovered "serious failings" in the sale of complex financial products to small businesses, just days after the rate-rigging affair emerged at Barclays.
Taxpayer-backed Royal Bank of Scotland has also confirmed it is being investigated for manipulating the rates at which banks lend to each other.
Treasury sources said its review, to be headed by an as-yet-undisclosed independent figure, would ensure a speedy response to the issue, resulting in amendments to the Financial Services Bill this summer.
Ministers are considering setting up a separate review into the professional standards of bankers.
Prime Minister David Cameron said the government would ensure "the criminal law can go wherever it needs to".
Asked about calls for a wide-ranging inquiry, he said: "Let's take our time, think this through carefully... That's what I'm determined to do, and that's what we will do."
But Mr Miliband said the Prime Minister was "out of touch" and warned that voters would not accept "the establishment closing ranks".
He called for an inquiry along the lines of Lord Justice Leveson's into media ethics and practices.
"I have news for David Cameron - the people of this country want a moment of reckoning for our banks," he told a Fabian Society conference in London.
"The British people will not tolerate the establishment closing ranks saying we don't need an inquiry.
"They want a light shone into every dark corner of our banking system. They want bankers held to account. They want the system rebuilt.
"Nothing less than a full public inquiry can do that. Sticking-plaster solutions will not heal this wound."
Barclays was fined £290 million by UK and US regulators for manipulating the rate at which banks lend to each other in the first of two scandals to rock the City this week.
On Friday, the FSA revealed separately that Barclays, HSBC, Royal Bank of Scotland and Lloyds Banking Group had agreed to pay compensation to customers who were mis-sold interest-rate hedging products.
Some 28,000 of the products have been sold since 2001 and may have been offered as protection - or to act as a hedge - against a rise in interest rates without the customer fully grasping the downside risks.
Serious Fraud Office investigators are in talks with the regulator over the scandal.
Former chancellor Alistair Darling argued the regulation of the banking industry has been too soft for too long, but said a costly public inquiry was not needed to fix the problem.
He told The Sun: "For 30 years, politicians have gone along with an approach that allowed regulation to be pretty skimpy.
"The last time big financial industry regulation went through the Commons, all three parties were extolling the virtue of having a minimum approach to regulation.
"Now we have the opportunity to put this right."
Mr Darling called for a three-pronged crackdown on the industry, with an independent watchdog with real teeth, new tighter laws and bank bosses laying down the law to their employees.
