It’s almost time for us to say goodnight, but not before a quick recap of the main political stories on this Bank Holiday Sunday. It’s been a busy day, as expected with just four days to go before polling day. Here's what's been happening:

- David Cameron has said he will not lead a government that fails to deliver a referendum on the UK's EU membership

- Labour leader Ed Miliband pledged to cut tuition fees to £6,000 a year and said he would not stand for re-election if he failed to do so

- Labour unveiled an 8ft-high stone with its manifesto pledges carved into it, which sparked social media fun

- Lib Dem leader Nick Clegg said his party would insist on a public sector pay rise as a condition of any coalition deal

- UKIP leader Nigel Farage warned that only UKIP could ensure there was a "fair and free" EU referendum and said pollsters and commentators were talking his party down

- Scotland's party leaders clashed over public spending cuts in the next UK parliament during the final set-piece TV debate before voters head to the polls

- In Wales the Conservatives accuse Labour and Plaid Cymru of being involved in an "unedifying squabble" over who to support if there is a hung parliament

- Newcastle hopes to be hot on the heels of Sunderland in being among the first to declare its results on election night

- A plaque was unveiled to mark the spot of John Prescott's 2001 punch.

Thanks for joining us – and hope to see you again tomorrow. Night all.

This was meant to be the most exciting election in British history. The first in living memory where no-one dared to predict the outcome. That still remains the case, so why are some complaining about how dull the campaign has been? Over to BBC political reporter Brian Wheeler., external

Ed Miliband's 8ft (2.4m) stone - engraved with Labour manifesto pledges - has drawn a fair amount of flak on social media. But the #EdStone, as it was quickly labelled, is just the latest in a long line of political props, some more successful than others. BBC News takes a look at the chequered history of political props.

The Guardian's Nick Watt reports that the former Conservative chancellor, Ken Clarke, has warned a second general election later this year after an inconclusive result on 7 May would resolve little - and probably produce a similar outcome.

He writes, external: "In a warning to the main political parties, which are making tentative plans for a second election as opinion polls suggest that Labour, external and the Tories are largely tied, Clarke said: 'You can get out of a hung parliament by having a second election but, not surprisingly, the public tends to return a parliament which looks rather like the first one.'"

Prime Minister David Cameron has been accused of "ducking" one of the last set-piece events of the general election campaign.

More than 2,200 voters are expected to put questions to the three main parties on issues including pay-day lending, social care and the living wage, at a rally staged by community-organising charity, Citizens UK.

Labour leader Ed Miliband and Lib Dem leader Nick Clegg will be taking part but it will be Culture Secretary Sajid Javid who represents the Conservatives.

Mr Clegg said the decision was typical of the Tories' "bloodless and uninspiring" campaign and Labour said it showed the PM was unable to defend his record.

However, Conservatives sources said that it had been made clear some time ago that Mr Cameron would be unable to attend due to campaigning commitments elsewhere in the country.

Comedian Steve Coogan has given Labour his backing ahead of next week's general election. In a video for the party he urged voters to back Labour, saying the Conservatives would "dismantle" the NHS if they won power.

He’s not the only celeb to endorse Ed Miliband's party this weekend. Writing in the Daily Mirror, cookery writer and TV presenter Delia Smith said Labour was the best party to "nurture and sustain" the NHS and would save Britain from being "cut adrift" internationally.

Earlier tonight during a BBC debate, Scotland's party leaders clashed over public spending cuts in the next UK parliament.

The live programme from Edinburgh was the last final pre-election debate between the Conservatives' Ruth Davidson, Labour' s Jim Murphy, the SNP's Nicola Sturgeon and Lib Dem Willie Rennie.

Ed Miliband's decision to set his party's six pledges in stone (yes, literally) has been causing a bit of a stir today.

Iain Martin derides the move in a piece for CapX, external: "It is such a mind-bendingly bad idea that it is difficult to figure out what on earth his advisers thought they were doing when they crafted this plan. Large slabs with writing carved on it suggest tombstones and in this context political death."

At an event for party activists earlier today, David Cameron praised his party's record in government.

He told a crowd in Nuneaton that the Conservatives had created jobs, grown the economy and cut the deficit. "Let's turn the good news in our economy into a good life for more people in our country", he said.

The position of the parties on Europe are set to be key both in the run-up to the election and in any possible coalition negotiations afterwards.

BBC political correspondent Ben Wright outlines the position of some of the main parties.

Calling all political geeks... your bank holiday Sunday is about to get a whole lot better. The legendary Peter Snow has dusted off his swingomenter and is taking viewers through "60 years of swing" over on the BBC Parliament channel. What better way to get in the mood for Thursday's election.

The Guardian

Political commentator Andrew Rawnsley is unhappy with the way this general election campaign is being run. It's "shrill yet sterile" and "a terrible let-down", with the big issues avoided and the public dodged, he writes in The Guardian., external

"It is not surprising that there seem to be an unprecedentedly large number of swithering voters this close to the moment of national decision. Where voters have expressed a yearning for more honesty, they have been met with evasion and obfuscation.

"Where we needed engagement between the political class and a disillusioned electorate, the campaigns have devoted their greatest efforts to protecting their leaders from the public. Where we needed a searching debate about our country, the voters are being asked to go to the polling stations wearing blindfolds."
