Jeremy Corbyn's speech on defence and security today has received qualified backing from the UKIP leader Paul Nuttall.

Commenting on a central theme of Mr Corbyn's speech - where the Labour leader highlighted a link between domestic UK terrorism and British involvement in conflicts overseas - Mr Nuttall said: "I tend to agree with Jeremy Corbyn on this.

"I was opposed to the war in Iraq. I was opposed to intervention in Libya, because it was obvious that what was going to to come next was going to be even worse...

"However I hope Jeremy Corbyn isn't using this as an excuse for what happened the other night. This was an Islamist terror attack and I just hope now that there isn't more of this around the corner."

The Shadow Attorney General, Shami Chakrabarti, says UK foreign policy is "used and abused" by terrorists in their justification for atrocities, such as the Manchester bomb.

She was commenting on Jeremy Corbyn's first speech after he resumed campaigning for the general election, where he pledged that a future Labour government would change British foreign policy, to one that "reduces rather than increases" the threat to the country.

Talking to Radio 4's The World at One, Baroness Chakrabarti said it was right for the Labour leader to say to troops that they would only be put in harm's way and deployed abroad when "there was a clear need".

The claim: UKIP says it can fund a big increase in NHS spending by cutting the budget for overseas aid.

Reality Check verdict: UKIP could save significant sums by cutting overseas aid, but how much will depend on how the economy performs over the next few years.

The SNP leader, Nicola Sturgeon, has said that she stands by her party's support for UK military action in Libya in 2011.

She was speaking after Labour leader Jeremy Corbyn linked British military interventions abroad with the terrorist threat at home and said the war on terror was not working.

Ms Sturgeon - visiting Scottish Gas apprentices in Edinburgh - said it was right that we should debate foreign policy but that terrorists must not be allowed to use it as an excuse for atrocities like the Manchester attack.

Lord West has warned against supporting the "radical Islamist narrative", following Jeremy Corbyn's comments linking UK foreign policy to terror threats.

The former Labour security minister Lord West has questioned some of the principles outlined in Jeremy Corbyn's speech today on security and terrorism.

In response to Mr Corbyn's highlighting of a link between wars the UK had fought abroad and domestic terrorist attacks, Lord West said he wished to avoid "platitudes".

He conceded that some conflicts had been counter-productive, citing the examples of Iraq, Libya and a decision to "stay on" in Afghanistan. But he argued that attempted terrorist attacks from Al-Qaeda dated back to the 1990s, before those British military actions had been undertaken:

"One was a car bomb attack in 1997 which we stopped luckily before it happened. Another was the poisoning of north London water supplies which would've killed over 100,000 people... These were happening way before 9/11 and of course 9/11 happened before we entered Afghanistan," he told the World at One.

"The only thing we were doing abroad - and our soldiers were dying - was to stop the genocide of Bosnian Muslims... It's all very fine Jeremy Corbyn saying he's going to assure our troops that they'll only go somewhere where there's a plan [but] to say that this will deliver lasting peace... Let's not have platitudes."

US Secretary of State Rex Tillerson has said “we take full responsibility” for leaks of information on the investigation into the Manchester attack - and added: “Obviously we regret that happened.”

Mr Tillerson said: “The President has been very strong in his condemnation and has called for an immediate investigation and prosecution of those who are found to have been responsible for leaking any of this information to the public.

“This special relationship that exists between our two countries will certainly withstand this particular unfortunate event.”

He was speaking at a press conference with Foreign Secretary Boris Johnson in London.

The Welsh Lib Dems are launching their manifesto for Wales in Hay-on-Wye today, saying Brexit is at the heart of their proposals.

Welsh Liberal Democrat leader Mark Williams says a second referendum is needed before Britain leaves the EU, in case the exit deal "wrecks the future for our children".

National campaigning by the political parties has resumed today after being suspended out of respect for those who died in the terrorist bomb attack on Manchester on Monday.

• Jeremy Corbyn has called for a different approach to the UK's foreign policy and said although the blame for atrocities like Manchester "is with the terrorists", we need to be "honest about what threatens our security" and be "tough on terror and the causes of terror"
• His comments have been attacked for both content and timing by the Conservatives and the Liberal Democrats, with the Tories accusing him of making excuses for terrorists
• Theresa May is at the G7 summit of world leaders in Italy, calling for a crackdown of extremist content online and more cooperation from social media platforms
• The IFS think tank has published its analysis of the parties' manifesto pledges and says the main two need to be more honest about how they are going to fund their policies

Shadow attorney general Baroness Chakrabarti tells the World at One it was "important for Jeremy Corbyn to address everyone in Manchester and everyone who puts themselves in harm's way directly" after what she calls "horrible character attacks" on him.

She says what she took from his speech was "there's absolutely no justification for these atrocities" but it's right to say to troops "when you are put in harm's way there is a clear need and there will be a plan".

UK foreign policy decisions are "used and abused" as recruiting tools, she argues.

If she were to become attorney general she would approve the case for military action where there is "a clear and pressing need for such an intervention", and it includes "a sensible, ethical" approach to peace-building and security.

Mr Corbyn wants to see people "pulling together", she says, not "character attacks", pointing out there was nothing in his speech about Theresa May.

Foreign Secretary Boris Johnson has condemned Jeremy Corbyn's speech in which he sought to draw links between the war on terror and attacks in the UK as "absolutely monstrous".

He said he found it "absolutely extraordinary and inexplicable in this week of all weeks that there should be any attempt to justify or to legitimate the actions of terrorists in this way".

Speaking alongside US secretary of state Rex Tillerson in central London, Mr Johnson told reporters: "This is a moment ... when we should be coming together, uniting to defeat these people, and we can and we will, not just in Iraq and in Syria but of course in the battle for the hearts and minds.

Defence Secretary Sir Michael Fallon has also criticised Jeremy Corbyn's comments on Britain's foreign policy:

Former MP and Labour minister Tom Harris has criticised the speech today by Jeremy Corbyn - linking Britain's involvement in wars overseas with terror attacks at home - saying that that he had "grave reservations" both on the tone and content of what Mr Corbyn was saying.

Mr Harris said: "He has spoken a great deal about the culpability of the West which is a theme which he has pursued for the last 30 years and he has said nothing at all about Islamism which is actually the root cause of domestic and international terrorism.

"I think he is buying into the Islamist agenda entirely."

The prime minister used her first one-to-one meeting with French President Emmanuel Macron since he took office earlier this month - held in the margins of the G7 summit in Taormina, Sicily - to press him on the forthcoming Brexit negotiations.

During the French elections, Mr Macron took a tough line on Brexit, backing the stance of EU negotiators who are insisting there must be progress on settling the terms of the UK's departure - including the financial settlement - before talks on a new deal can start.

"On Brexit and the Article 50 process, the Prime Minister reaffirmed her wish for early clarity on the position of EU citizens in the UK and vice versa," a spokesman said. "She also made clear that Britain and the 27 EU member states should be discussing our future relationship with the EU at the same time as discussing the terms of our withdrawal."

No 10 said the French president offered support for Mrs May's plans set out at the G7 to pressure tech companies like Facebook and Google to do more to take down "harmful" extremist content from the internet.
