If the daily politics show had included the SNP in todays debate it would have heard that in Scotland we already produce over 45% of our electricity needs through renewables and will reach over 50% by the end of this year. By 2020 we will have a figure of 100%.

The prime minister has said "we can do more" to deal with the problem of EU migrants. He said he was delighted the EU has called an emergency summit for Thursday.
Mr Cameron said what was needed was a "comprehensive plan" which involves elements of search and rescue, doing more in the countries migrants come from and cracking down on "terrible people traffickers"at the heart of the problem.
He said Britain would "lend a hand".
Looks like a tropical hideaway but the BBC's Ben Brown is actually at the Eden Project near St Austell, Cornwall. He's inside a biome - one of the biggest "greenhouses" in the world. Ben says each of the six constituencies in Cornwall is a marginal and the fight is principally between the Conservatives and the Liberal Democrats. In 2010, the Conservatives won three seats and the Liberal Democrats the other three. The Conservatives won one of its seats by just 66 votes.

Despite all the focus on Nicola Sturgeon, today in particular, researchers at Loughborough University say women have featured in barely a fifth of media coverage of the general election so far.
Academics from the university’s Communication Research Centre are conducting a real time news audit of the election campaign. In their latest report, external the research team found that female MPs are receiving "significantly less media coverage than their male counterparts", with 86% of politicians featured in election coverage so far being male.

The 2004 offer of devolution for the north east of England was very poor and "simply not good enough", says a former Labour MP who has founded a new party. Hilton Dawson of The North East Party (NEP) told Jo Coburn on the Daily Politics earlier today that "we are losing out in comparison with the good folk of Scotland". Mr Dawson said the NEP was committed to the UK, but it should be fair for all reigions as he spoke about levels of investment, taxation and opportunities. Watch the interview

Getting fed up of people calling the financial meltdown "a Labour disaster". It was a global financial crisis. Stop trying to blame one government for the whole thing.
Lib Dem leader Nick Clegg says his is the "party of education".
Campaiging in the south west of England, he told reporters it would be a "good thing" to run the education department on his party's terms, after what he said were the zany ideological "gimmicks" of the Gove era.
Some reporters with him are seeing this as a hint that the Lib Dems might seek control of the Department for Education as part of any coalition deal.
A poll of 1,000 students by research agency YouthSight has found Labour remains their first choice.
Recent surveys by the organisation have charted the Green Party's rise among students, but the latest reveals its share fell from 28% in February to 15% this month. Labour had a 35% share, followed by the Conservatives on 25% and then the Greens.
The Liberal Democrats, SNP and UKIP all made gains between February and April, but stayed in fourth (9%), fifth (7%) and sixth (6%) positions respectively.

I find it difficult to listen to politicans talking about energy and global warming and not one mentioned the roof of every house in the UK which should be covered with solar panels... Instead of seeing the odd roof with solar panels making money for the roof owner lets have every roof making money for the country and curing the dole queue by the installing the roof panels.

Labour peer Lord Foulkes says the British government "must shoulder some of the blame" for migrant deaths in the Mediterranean. The European Union, in a decision backed by the UK, withdrew support for the Mare Nostrum search and rescue operation last year. It has been replaced by a smaller operation to which Britain contributes.
Lord Foulkes, who was a minister at the Department for International Development, has written to Foreign Secretary Philip Hammond urging him to support a wider search and rescue operation off Italy's coast.
He said Mr Hammond should press the EU "to restart such operations immediately, and to offer British ships and aircraft to aid such efforts".
Quote Message"I do so because I believe this government, we as a nation, and the wider European Union must shoulder some of the blame," he said. "The simple fact is, unless more boats are sent out to patrol the region and rescue people, more innocent lives, including those of children, will be lost in the days and weeks to come."
