Prime Minister David Cameron has praised Newcastle-born Nobel prize winner Peter Higgs who predicted the existence of a fundamental particle which has been named after him.
Professor Higgs was born in Newcastle in 1929. His discovery of the Higgs boson was ratified by scientists at Cern last year. The Prime Minister praised Professor Higgs and the UK's "world-leading" universities.
Earlier today, September 30, the Prime Minister told this programme decriminalising drugs was not the right thing to do. David Cameron said it would only make them more available and increase their use.

Casee Leigh asked via Facebook: Do you think you can live on £53 a week?
David Cameron's response: Of course no one thinks living on benefits is easy. And it appears that the person you are referring to may have actually been receiving more than that.
But what's important is that we are fixing the tax and welfare system so that it works for hardworking people. We're cutting income tax for 24 million people, taking 2.2 million out of income tax altogether and making work pay by introducing Universal Credit.
But let’s also be clear: the benefits system provides a significant range of support for people when they need it - from housing help, to financial support when people fall ill and can't work, help for people who are caring for others, help for people in work and on a low income - I could go on.
Lara Turner asked via email: How do you legitimise the choice to prioritise unfair cuts to the welfare bill, over boosting the economy by chasing tax avoidance, particularly by large corporations?
David Cameron's response: I don’t accept that cuts to the welfare bill are unfair. We live in a country where one pound in every three the government spends goes on pensions and benefits.
This is simply not affordable. So we are reforming welfare in a way that is sensible and fair: making sure that work pays and that help goes to those who genuinely need it.
What would be unfair is leaving another generation locked in the benefits system, leaving the taxpayer to pay for those who choose not to work, and leaving our children’s generation to pick up the rest of the bill.
And it’s not a case of prioritising welfare reform over tax avoidance – we’re doing both. In fact we’ve already committed hundreds of millions into clamping down on this – and I’ve made dealing with tax avoidance a top priority for the G8 which Britain is hosting this year.
We are getting the leaders of the world’s richest countries around a table to deal with this.
Shaun Griffiths asked via email: Why was the criteria for PIP (Personal Independence Payment) changed from 50 metres to 20 metres?
David Cameron's response: We want to make sure that support goes to those who need it the most.
Higher rate mobility payments are meant for the most disabled - people unable to walk or virtually unable to walk. We asked experts for their views - and we've now decided that 20 metres is a fair criteria to set.
But it’s not a cast iron limit. If you can move further than 20 metres but can't do it safely, reliably, repeatedly, or in a reasonable time period - then you can still qualify for the enhanced rate payments.
I know how difficult some of our changes to the welfare system are. But they're the right thing to do. Under Labour, people were often put on Disability Living Allowance for life without any regular assessment to see if their condition had changed.
The new system will include a new face-to-face assessment and regular reviews. Because for us, it's about looking at people as individuals, not labelling them by their condition.
Ross Casement asked via email: At a time when you are slashing benefits to poor families and calling for austerity, how can you justify £10 million for Margaret Thatcher’s funeral?
David Cameron's response: Regardless of your views on Mrs Thatcher, we can all agree that she was a towering figure in our history: the first woman Prime Minister; a statesman who helped end the Cold War, won the Falklands war and put our country back on the map.
I believe it’s right that we should mark those exceptional achievements with a proper occasion.
The Prime Minister vigorously defended his so-called controversial 'bedroom tax' in an interview with ITV News. Asked if it was fair that children "bear the brunt of this kind of policy", he said:
"There is a human impact on the entire country that we currently spend £23 billion a year on housing benefit, that is more, to put it in context than we spend on the entire transport and home office budgets.
"We only spend £33 billion on our entire defence system for the UK. So it's not sustainable to go on with a housing benefit system and a benefit system."
David Cameron has branded some reaction to the death of Baroness Thatcher as "pretty distasteful".
The Prime Minister said he thought the majority of national feeling was to grieve for the loss of a great leader, but conceded that sections of society did not agree.
Asked if he was disappointed about animosity towards the former prime minister, he said:
– David Cameron, Prime Minister
"I think the overwhelming sense across the country, and you can see it yesterday in the House of Commons, is that we are mourning the loss of someone who gave a huge amount to this country, that was an extraordinary leader.
"I think that is how the overwhelming majority of people feel.
"Of course, some people won't agree with that but I think that some of the scenes we have seen are frankly pretty distasteful, but people should be responsible for themselves."
Prime Minister David Cameron said Parliament would be recalled on Wednesday "for a special session in which tributes will be paid" to Baroness Thatcher.
