It is put to John McDonnell that although wages have stagnated employment has been going up. 

Robert Peston reflects that some commentators have said this is because the cost of employment in the UK is lower and there is a risk Labour's plans would bring a growth in unemployment. 

Mr McDonnell says "absolutely not".  

"We're the only major developed country where we've got growth but wages are stagnating or going backwards," he adds. 

"All we're asking for is fairness". 

Mrs May is asked about whether she regrets voting over the Iraq War. 

She said she voted in the Commons in the way she "believed was right" at the time.

Mr McDonnell is asked about plans that trade unions could negotiate sectoral wage deals - something Peston describes as a "revolution" over how pay is set.

Mr McDonnell says collective barganing has declined over the last 20 years, which has eroded wages. 

He says we can't live in a society where British nurses are reportedly using foodbanks because of the wages they get.  

Shadow chancellor John McDonnell has been interviewed on Peston on Sunday. 

He is asked about the 20-point plan to end the "rigged economy" in the workplace and it is put to him that it is the biggest shift of power to the trade unions since the post-war period. 

Mr McDonnell says it is more about giving people security. He says zero-hour contracts will be ended under Labour.   

Mrs May is asked about whether the election has been called because 30 Conservative candidates or agents are under investigation by the CPS over election expenses. 

She says that is not the reason it was called - it is about the national interest and future of the country she says. 

Mrs May, who like Tim Farron is also a Christian, is asked if she thinks gay sex is a sin -  to which she responds "no" immediately. 

The PM is asked if the richest people - perhaps those living in £5m houses - should pay more. 

Mrs May says the top 1% are paying more under the Conservatives than they did under any Labour government. 

She says the tax system should be "balanced" and she wants to reduce taxes for "working people". 

Mrs May is asked about having to pay a separation fee from the EU - perhaps as much as £40bn-£60bn.

She is asked if she will agree on the money before everything else.

Mrs May says she wants to agree on a trade deal and the EU arrangements at the same time. 

She disputes that EU leaders want to discuss money first, but agrees the two sides are in agreement about the rights of UK people living in the EU and EU citizens living in the UK. 

Mrs May is asked if she still believes that no Brexit deal is better than a bad deal. 

She says she does. 

Marr is asked about reports her meeting with European Commission President Jean Claude Juncker went badly. 

She sidesteps this question, but says it shows there will be times when the negotiations will be tough which is why "strong and stable" leadership is needed.

Mrs May is asked about what happens when pension schemes collapse. 

She says the Tories would bring in new powers for the pension regulator to make sure workers had reassurance over their pensions. 

Asked about whether people could be prosecuted for their role in it, she said there would be greater powers. 

Norman Smith, the BBC's Assistant Political editor, reads between the lines of what the prime minister has been saying.

Mrs May is asked about if the triple-lock on pensions is safe. 

She says under the Conservatives the state pension will go up every year of the next Parliament but she says how that increase is calculated will be decided in the manifesto. 

On the social care budget Mrs May says short term measures have been taken - £2bn extra to the budget - but in the medium term good practice needs to be spread across the country, such as how hospitals work with social care providers.  

She says there is also a long term plan but Marr will have to wait for the Conservative manifesto. 

Mrs May is now asked about her former pledge to never raise income tax, NI or VAT and whether it will be honoured. 

Mrs May says there are no plans to raise tax but she does not want to make "specific" plans about tax unless she can deliver them.

She adds that the Tories are a lower tax party. 

Mrs May says the government is introducing a fairer system of schools funding.

Marr mentions the per pupil funding and says a re-think is surely needed. 

She reiterates that a fair funding system is needed. 

Mrs May is now asked about there being a £3bn cut to primary school budgets by 2020. 

She says the government said it would protect the core schools budget. 

Mrs May says funding into schools is at record levels, but Marr ask her about how there are more pupils than ever and per pupil funding is falling.
