The Lib Dem Leader, Tim Farron, was challenged on his party's plans to restrict police surveillance powers. Did he still believe those plans were right in the light of the Manchester terror attack?

Mr Farron said the security services "need to be given the resources to make use of the powers they already have" and repeated his party's pledge to give £300 million for additional community policing.

Reality Check

The SNP's Angus Robertson said: "We need to invest in the police, not cut them, as has been the case in England - in Scotland we have managed to maintain police numbers."

Policing is devolved in Scotland and Northern Irealnd.

It’s true that in England and Wales, both the funding for police and the number of police officers has been cut since 2010.

Police spending in England and Wales has been cut by 20%, external and there are 19,000 fewer police officers.

In Scotland, police numbers have risen more or less continuously for the past 30 years.

Reality Check

UKIP leader Paul Nuttall has been talking about his plan to increase NHS spending by cutting the international aid budget.

Currently, the UK spends 0.7% of national income on international aid, which is provisionally set to be £13.3bn for 2016. That's a bit more than £30m a day.

UKIP wants to spend £9bn of that on the NHS and £2bn on social care.

Paul Nuttal says foreign policy wasn't to blame for Manchester.

But he calls on the other politicians to "have the courage to name what it is" - Islamist extremists.

Mr Nuttall says 20,000 more police officers back on the beat and 7,000 more prison officers is part of their policy to tackle it.

But he also gets applause after saying he can't believe the UK doesn't revoke the passport of anyone who goes to fight in places like Libya and Syria. He also says more needs to be done to address radicalisation in UK mosques is the answer.

The 46-year-old former college lecturer, and father-of-four, has been the Liberal Democrat leader since 2015.

He voted against tuition fees and took on the role of Lib Dem president, rather than a ministerial job, during the coalition years.

Amber Rudd stresses that "the first job of any government is to keep people safe".

"The way we try to stop them (terrorists) is by supporting security services and counter-terror police."

She insists we can "live within our means and protect communities".

Then she takes aim at Jeremy Corbyn for "boasting that he had opposed every piece of anti-terror legislation - he must be held accountable".

Caroline Lucas is the Greens' first, and so far only, MP and after seven years in the Commons she is the face of the party for many voters.

She was its first leader, elected in 2008 when the party abandoned its long-standing practice of having a male and a female principal speaker. After a break she is now back, as co-leader of the Green Party of England and Wales.

Jeremy Corbyn says what happened in Manchester was "unbelievably abominable".

He says it is the people responsible for the attack who must take the blame.

But he says questions have to be raised about the number of cuts to police forces, which the Labour Party will "restore".

He also talks again about his points on foreign policy, saying when you intervene in somewhere like Syria, "the consequences carry on".

A former business woman, who became an MP six years ago, Amber Rudd has had a meteoric rise through the Conservative ranks to the position of home secretary.

The 53-year-old mother-of-two is seen as a "safe pair of hands" but also a tough debater. She clashed with Boris Johnson in a televised EU referendum debate, when she was campaigning to keep Britain in the EU. She is now backing Brexit.

She was once married to writer AA Gill, who died last year, and made a brief appearance in the film Four Weddings and a Funeral.

She has been MP for Hastings and Rye since 2010 and was Energy and Climate Change Secretary before being promoted to the home office job.

The next question is on making the UK a safer place.

Angus Robertson described what happened in Manchester as a "horror" and says people need to "back the police and our security services".

"We are right to question interventions" in countries such as Libya, he adds, and shouldn't be spending more on bombing than on rebuilding.

Paul Nuttall says UKIP will scrap the HS2 rail project to raise money, saying that the only place to benefit will be London if it goes ahead.

He also says his party will get rid of the Barnett formula, used to decide public expenditure allocated to Scotland, Northern Ireland and Wales, and will also get a dividend from leaving the EU and scrap the foreign aid budget.

The latter, he says, will then be invested into the NHS.

Reality Check

Amber Rudd said that there are 3 million EU citizens in the UK and 1 million UK citizens residing elsewhere in the EU.

The figures are correct. The number of EU citizens living in the UK is estimated at 3.2 million, external, according to the latest figures from the Office for National Statistics (ONS).

The latest estimate from the ONS, external for the number of UK citizens living in other EU countries is about 900,000.
