Election update, May 3: under 100 hours to go — polling, promises and a princess

Perhaps unsurprisingly, almost all newspaper covers today are dedicated to the arrival of the royal baby.

In other news, the Independent gives the three main party leaders' last pitch to the public. According to the front page, David Cameron's priority is not just the economy but issues such as child poverty; for Ed Miliband the election is a battle of two ideas on how to run the country; Nick Clegg's pitch is that he will not go into a Conservative coalition against the collective will of his party.

We've published brief factchecks on manifestos from all three parties: the Conservatives,  Labour and the Lib Dems. Look out for our full manifesto report out early next week, and sign up to our newsletter to hear about it first.

Along similar lines, the Observer's front page reports on the possibility of a renewed Conservative-Liberal Democrat coalition, with senior MPs saying that the negotiations could last weeks rather than days. The article also warns about the prospect of Britain facing a period of instability after the election on Thursday. For more information, see our guide on the process of forming a government.

And with under 100 hours to go before Thursday's general election and the continuing likelihood of a hung parliament, opinion polls are covered in the Sunday Times and the Mail on Sunday, as pollsters try to predict the results. We'll be bringing you a guide on what to look out for in opinion polls early next week.
