The centrist says Le Pen's "new franc" will fall in value "by 20% to 30% overnight", he says.

The BBC's Gavin Lee picks up on a theme from an earlier vote...

"Euro is the currency of the bankers, not of the people," says Le Pen.

She accuses Macron of playing on "Project Fear".

She says the British were also fed plenty of fear over their future after Brexit. 

“We must return to our national currency, it’s key,” says Le Pen. 

Responding to Macron, she says banks and large companies will have a choice as to whether they pay in euros or a French currency. 

Individuals, meanwhile, will return to a French currency. 

Macron says this will not work. 

How can a big company pay in euros on one hand and pay its employees in another currency - "it's nonsense," he says.

What currency would France pay its national debt in, he asks.

"Chirac-Mitterrand in 1988 was the The Young Girls of Rochefort by comparison," Europe 1 journalist David Abiker tweets, recalling the 1967 seaside musical and a presidential debate remembered for its frostiness, rather than its fire.

He asks Le Pen whether she wants to leave the euro and return to the franc.

The National Front's policy on the euro has been vague, with suggestions France could either leave or have two currencies operating at once - both the euro and a new national currency.

"I am a European and I want to save Europe. I want to wrench Europe from the hands of the EU, which is wrecking it," says Le Pen. 

She wants full control of currency, of borders and of trade agreements.

“No one knows the name or face of the [EU] commissioners, who were not elected.”

Macron:

• Reform the EU by establishing a separate eurozone budget
• Promote free trade deals like Ceta - the EU-Canada deal 

Le Pen: 

• Repatriate powers to France and hold an in/out referendum on France's EU membership
• Restore full border controls, leave the Schengen open borders system, appoint 6,000 new customs officers

The debate has moved on to France's place in the EU, an issue which divides Macron and Le Pen almost like no other.

He accuses Le Pen of blaming him for everything that has gone wrong in France in the past.

"I take responsibility for what I've done, mot more," he says.

But Le Pen says he represents a continuation of President Hollande.

They are shouting over each other again, like a playground squabble.

Le Pen tells Macron: "We now call you Hollande Junior. That’s your nickname."

On a lighter note, bloggers are discussing how best to translate "poudre de perlimpinpin", which Macron accused Le Pen of offering voters. It seems the consensus is that it means "snake oil", a product or recommendation with no use. Just one of many insults flying to and fro in Paris tonight.  

He wants fines for acts of delinquency.

It's intolerable for police that the court process for suspects takes a long time, is complex and often does not lead anywhere, he says.

He says he wants 10,000 extra police officers.

He also says delinquency is becoming "intolerable" and promises police who "know the terrain" and spend more time out and about.

Le Pen says foreigners who commit a crime do not currently have to leave the country after they have served their sentence, and they should.  

She also wants more judges and prisons.

The debate has just moved on to law and order. "What for you does zero tolerance mean?" a moderator asks. 

How Guardian correspondent Kim Willsher sums up the debate so far:

Algeria's War of Independence against France "divides our country", says Macron, but he says he wants to "move to a new stage".

"I'm not in repentance or denial," he says.
