A little earlier, Radio 4's PM looked at the restarted election campaign with Matt Chorley of the Times and former Labour strategist turned pollster Deborah Mattinson.

She said that focusing on Theresa May's wobble on Monday over the Tories' social care policy would have made more sense tactically for Jeremy Corbyn.

However, following the Manchester attack, the Labour leader wanted to articulate his views on foreign policy and security.

"This was a very high risk strategy by Jeremy Corbyn," she argued, as Labour tends to lag behind the Conservatives on security in voters' estimation.

Ms Mattinson thinks Mr Corbyn "figures he has nothing to lose". Meanwhile, Theresa May, who remains ahead in the polls, does have something to lose but is also adopting a high risk strategy of her own.

Radio 4 PM

The election campaign is restarting, but has the political vacuum of four days affected the parties and the leaders?

Times journalist Matt Chorley tells Radio 4's PM that if he were advising Jeremy Corbyn, focusing on Theresa May's "worst day of campaigning" before the break "would have made more political sense", rather than restarting on a different tack.

Given that the Conservatives had a "bit of a wobble over social care" he predicts that they will restart by focusing on Brexit by reminding voters "who do you want to go to Brussels?"

Theresa May has said the threat posed by the so-called Islamic State group, or Daesh as it is also known, was taking on a new form and had to be confronted.

"The Daesh threat is evolving rather than disappearing", she said, as she warned that the threat from terrorism was moving "from the battlefield to the internet".

Speaking at the G7 summit in Sicily, the Prime Minister added: "This week the United Kingdom suffered one of the worst terrorist attacks in our history. The murder of innocent citizens and the deliberate targeting of children appalled people at home and around the world.

"Today G7 leaders have joined Britain in condemning this barbaric act of violence. It is at moments such as this that we are reminded of the fundamental importance of this unique group of nations and the unity that our memberships affords."

All the G7 countries were facing a threat from terrorism, said Mrs May, so "now more than ever we must strengthen our resolve to overcome this threat together".

The South Wales constituency of Gower is the UK's most marginal constituency.

It was held by Labour for more than 100 years but lost in 2015 to the Conservatives with just 27 votes in it.

For Radio 4's PM, Carolyn Quinn hears mixed views from locals and discovers the vote could be just as tight in 2017.

Foreign Secretary Boris Johnson has said Jeremy Corbyn "should be ashamed of himself", following the Labour leader's speech on linking British foreign policy and the threat of terrorism at home.

Speaking to the BBC's chief Political Correspondent Vicki Young, Mr Johnson said: "We can't follow the logic of the terrorists and start blaming ourselves or our society or our foreign policy.

"This has been caused not by us - as Jeremy Corbyn would have us believe - it's been caused by a sick ideology, a perverted version of Islam that hates us and hates our way of life. And to say anything now to legitimise or justify those who have carried out the atrocity in Manchester is absolutely obscene and I think Jeremy Corbyn should be ashamed of himself."

Mr Johnson said Jeremy Corbyn had "spent a political career sticking up for terrorists, sympathising with the IRA, with Hamas, with Hezbollah, and indeed blocking every single piece of anti-terrorist legislation in the last 30 years".

Jeremy Corbyn has refused to give his personal support for the renewal of Trident nuclear weapons, despite it being in Labour's manifesto.

The Labour leader said Trident renewal would go ahead because MPs had voted for it and the Labour Party backed it.

But he repeatedly declined to say whether he agreed with it, in an interview with the BBC's Andrew Neil, to be broadcast later on BBC One.

And he said nuclear weapons would be included in a defence review if Labour won power on 8 June. Read more

Has the Manchester attack and subsequent national security alert influenced the election?

"Voters very keen to say this is not going to affect how they vote," pollster Deborah Mattinson tells PM on Radio 4 - though she's not sure she's convinced by that herself.

Matt Chorley, from the Times, thinks voters "can probably separate" the Manchester atrocity and the election campaign.

Pointing to a YouGov poll for his newspaper,, external which put the biggest two parties just five points apart, he says the Conservative lead over Labour has been "creeping down".

He argues that it is linked to the row over the Tories' social care policy in England.

Deborah Mattinson says a "sense of jeopardy" in Conservative ranks could galvanise Tory voters not to take the risk of a Labour victory.

She adds that this is one poll and she would want to see "many more polls" pointing to a narrowing of the gap with Labour before she believes the opposition is catching up.

Jeremy Corbyn has given his first speech of the restarted election campaign, focusing on counter-terrorism and presenting what he described as Labour's different approach to domestic and foreign policy.

Daily Politics presenter Jo Coburn got reaction from shadow international trade secretary Barry Gardiner and Conservative candidate Johnny Mercer.

In his speech earlier on Friday, Jeremy Corbyn channelled a previous Labour leader when he said he would be strong on terrorism, strong on the causes of terrorism.

But the substance of his message was miles away from Tony Blair's approach to foreign policy.

There is a pretty obvious reason why Mr Corbyn drew a link between intervention in foreign wars and acts of terrorism here. He believes it.

He has said similar things during his two Labour leadership contests - except this time he points out that this view is shared more widely by "experts".

Those who flooded in to Labour in 2015 to support his leadership - from the Greens, the Stop the War coalition or those who simply got involved in politics for the first time - will be delighted to hear him set out a direction that is distinctive, not just from the Conservatives, but from recent Labour leaders.

They may be encouraged to step up their campaigning as a result. But the party is divided between recent and long-standing members. Read more from Iain

Reality Check

This morning I heard one of those lines that's obvious when you think about it, but hadn't occurred to me before.

It came from Robert Joyce, a tax expert from the Institute for Fiscal Studies, which held a briefing on the parties' manifestos.

He was talking about raising taxes for high earners.

If you have somebody currently paying the 45p tax rate, you raise that to 50p and there is no change in behaviour then the excequer gains an extra 5p in the pound.

But if they decide to try to reduce their tax bill by saving more into their pensions, for example, or indeed decide to work fewer hours, then you lose 45p in the pound as well as some National Insurance.

So you only need one person in 10 to change their behaviour and you don't make any money from raising the tax.

In the wake of the Manchester bombing, Theresa May is using the G7 summit in Sicily to try to galvanise tougher international action against terrorism.

The prime minister chaired a session on security and told her fellow leaders that more should be done to get internet firms to identify, remove and block extremist material online. She also urged them to help countries in the Middle East tackle foreign fighters who have traveled to the region to join so-called Islamic State.

She said the expertise in policing, evidence gathering and intelligence sharing that G7 countries could provide would help countries like Iraq prosecute and deport foreign fighters seeking to return home.

A joint statement setting out the G7 plans on counter terrorism is expected shortly. Mrs May will then leave the summit early so she can return to the Manchester investigation and the election campaign.

The Manchester suicide bomb was the latest manifestation of Islamist-related violence in Europe. Of all European countries, France has been most affected having suffered a number of attacks perpetrated by French citizens.

It has been grappling with difficult questions around integration and national identity.

Daily Politics reporter Ellie Price looks at what happened in France and how the country responded.

The Institute for Fiscal Studies (IFS) has analysed Labour and Conservative manifestos and compared their plans on public spending, the public finances and reforms to taxes and benefits.

IFS deputy director Carl Emmerson offered analysis of what the bigger parties are offering voters when he spoke to Daily Politics presenter Jo Coburn and commentators Ian Collins and Rafael Behr.

Voters want to know how the extra billions for schools and hospitals that politicians pledge are going to be paid for, which taxes are going up and which benefits are being cut.

But that means cold, hard numbers - something that some politicians seem to have trouble with as these election interview clips recall.

Chancellor Philip Hammond has accused Jeremy Corbyn of “justifying or excusing” the conduct of terrorists by “talking about what Britain does in its foreign policy”.

Mr Hammond said: “We have to be very careful we don’t imply that we are justifying or excusing in any way the conduct of these horrific terrorist actors. Whether it’s talking about what Britain does in its foreign policy as Jeremy Corbyn has been doing this morning.”

He added: “We have to be very clear. Terrorism, attacks on innocent civilians, are always wrong and the only people to blame for them are the people who carry them out.”

Mr Hammond was taking part in a Q&A with students at Royal Holloway, University of London.

The chancellor also rejected accusations that he has “underfunded in some way our security and counter-terrorist response”.

He said he had prioritised counter-terrorism policing within police budgets and pointed to £1.9bn of additional spending in last year’s Budget for the security and intelligence services.

Jeremy Corbyn's comments on terrorism are "entirely wrong" and make him unfit to be prime minister, according to Democratic Unionist Party deputy leader Nigel Dodds.

"Responsibility for terrorism lies where it always does, with those who carry it out," Mr Dodds said.

"Those who excuse, justify or celebrate terrorists only make the job of the security forces harder. They deserve our wholehearted support, and not the persistent abuse they have received from Jeremy Corbyn, John McDonnell and Diane Abbott for more than 30 years.

A spokesman for Operation Inherent Resolve, the US-led coalition fighting the so-called Islamic State group in Iraq and Syria, has said "we must not allow Isis to have sanctuary to plan these attacks".

Col Ryan S. Dillon, speaking on Radio 4's World at One, said the Syrian city of Raqqa has been a "staging and a planning operation location for Isis, particularly for attacks against Paris and Berlin".

He went on to say: "We cannot allow [IS] to continue with their twisted ideology and attack the West and elsewhere."
