While doctors strike, Health Secretary Jeremy Hunt is hosting a "global patient safety summit" in London and has said he wants "new era of openness" in the NHS.

Trusts in England have been ranked by their ability to learn from mistakes, as part of several changes designed to improve patient safety.

The "learning from mistakes league" rates 120 trusts outstanding or good, 78 with "significant concerns" and 32 with a "poor reporting culture".

Other measures include legal protection for staff who admit mistakes, and new medical examiners to review deaths.

A patient safety charity welcomed the moves but said it remained "concerned".

Katherine Murphy, chief executive of the Patients Association, said: "Whatever the rights and wrongs of the arguments put forward by either side, the failure to resolve the differences by agreement is bad for doctors, bad for the taxpayer, but above all bad for patients and the NHS."

Health Secretary Jeremy Hunt also told MPs that England's standards of safety compare well to other countries. And he claimed he wants England "to lead the world" in terms of safety.

But he goes on to say that a "culture change" is needed in the NHS.

In response to Ms Alexander's claims, Mr Hunt quoted the founder of the NHS - Nye Bevan - who he said claimed the British Medical Association was full of "politically poisoned people".

Shadow health secretary Heidi Alexander has spoken in the Commons and accused Health Secretary Jeremy Hunt of taking a "kamikazee approach" in enforcing the junior doctors' new contract.

She said the NHS was under-funded and under-staffed and said Mr Hunt was not giving it "a fighting chance".

Ms Alexander said he was to blame and had "lost the goodwill of staff on which the NHS relies".

She then accused Mr Hunt of being "shy" in visiting the NHS frontline recently.

The ante has certainly been upped in the increasingly acrimonious dispute between junior doctors and the government in England.

Today's strike sees medics stage a walk-out for the third time - with two more stoppages to follow next month - while lawyers prepare a legal challenge to fight the imposition of the new contract.

But while the medical profession busies itself, the government's tactic is relatively simple: it's hoping the whole thing will just go away.

Now that may seem pretty far-fetched given the row has dominated the headlines in recent months.

But there's good reason to think it will succeed. Firstly, the chances of the judicial review the British Medical Association is pursuing actually stopping the imposition is, by all accounts, slim.

And with Europe dominating the media's attention, the government's spin doctors seem pretty confident the issue won't be given the airtime it has had to date.

The chairman of the junior doctors committee of the BMA, Johann Malawana, said he "deeply regrets" causing disruption.

He said: "This is the last thing we ever want to do. The thousands of doctors that are currently standing on picket lines would much rather be in the hospital. 

"But unfortunately, the government has pushed us into this. And we basically have very little option, the government is not willing to talk to us, not willing to come to a negotiated settlement, the only option open to us is unfortunately industrial action."

Jeremy Taylor, chief executive of National Voices, a coalition of 160 health and care charities, has called for doctors and ministers to get back around the negotiating table.

He said: "It’s not acceptable for periodic strikes to become normal in the NHS.

"If both the government and the BMA were as focused on patients as they say they are, then they would be making all efforts to resolve this dispute.  

"As it is, patients are suffering and the two sides aren’t even talking."

Doctors in England who are taking part in the industrial action are running free life-saving training sessions in their communities. 

Up to 25 walk-in #LittleLifeSavers classes are being held countrywide by junior doctors striking in a dispute with the Government over a new contract. 

In Ashington, near Horsham, West Sussex, 12 junior doctors volunteered to take part in three resuscitation stations - basic adult and child life support and managing a choking baby.

Doctors are also letting members of the public perform full resuscitation techniques on mannequins.

The third strike by junior doctors in England in their contract row with the government is under way.

The walkout, which comes after ministers announced last month they would impose a new contract, started at 08:00 GMT and will last 48 hours, though medics will provide emergency cover in hospitals.

But how effective are strikes? Victoria spoke to a junior doctor, a member of the Rail, Maritime and Transport workers union and a midwife who went on strike in 2014.

A poll of 860 adults by Ipsos MORI for the BBC showed 65% supported doctors going on strike, almost the same proportion as backed them ahead of the walkout last month.

The poll did show an increase in the proportion of people blaming both sides for the dispute,now standing at 28%, up from 18%.

Victoria hosted a discussion with one junior doctor and by eight members of the public, to see how they felt about the latest strike.

As junior doctors' stage a third strike in England, BBC's Jim Reed explains the reasons for the row.

Scotland, Wales and Northern Ireland are not affected by the government's imposed contract for junior doctors.

The governments in Wales and Scotland have decided not to introduce a new contract - for now.

And in Northern Ireland, junior doctors aren't on strike, because negotiations between them and the local health minister Simon Hamilton are still going on.

A Department of Health spokesman said: "Patients have so far seen more than 19,000 operations cancelled as a result of the BMA's irresponsible and unjustified industrial action.

"The new contract, 90% of which was agreed with the BMA and endorsed by senior NHS leaders, is a very good deal for doctors and the NHS."
