Following on from The Guardian‘s endorsement, The Observer becomes the second newspaper to back the LibDems:

The vital context for this election is the twin crises in our economy and our politics. On both issues most credit accrues to the Liberal Democrats. Their Treasury spokesman Vince Cable was prescient in warning of an unsustainable debt bubble; Nick Clegg pushed for greater openness about expenses long before the scandal erupted.

The Lib Dems have in recent years developed a habit of getting things right. They were first of the big three to embrace environmentalism, first to kick back against the assault on civil liberties, alone in opposing the Iraq war…

There is only one party on the ballot paper that, by its record in the old parliament, its manifesto for the new one and its leader’s performance in the campaign, can claim to represent an agenda for radical, positive change in politics. That party is the Liberal Democrats. There is only one way clearly to endorse that message and that is to vote Liberal Democrat.

Meanwhile, the Sunday People has followed up its earlier cogent arguments, based on experience in other countries, in favour of Parliaments where no one party has an overall majority (yes, the Sunday People) by coming out for proportional representation:

If we are to change our old political system it can only be done by introducing a new voting system.

Which is why today The People announces it will be campaigning for proportional representation.

The Independent on Sunday also backs reform and goes one step further in talking about tactical voting:

So today we begin our campaign for a fairer system with a plea: in this election of all elections, the opinion polls, in signalling a hung parliament, suggest a historic opportunity for change that, as Nick Clegg suggests to us today, may not recur for a generation. And that compels us to suggest that readers should consider voting tactically on Thursday.

What do we mean by that? As the Tories are opposed to electoral reform and are ahead in the polls, we are asking voters in 85 key constituencies to vote for the candidate best placed to frustrate David Cameron…

If you are convinced by the Tories, then please give Mr Cameron your considered support. But if you believe that we are on the cusp of a once-in-a-lifetime opportunity, then join with us, and vote for the change that really matters. Use your democratic right to enhance the democratic rights of all. Vote for a hung parliament, and a better, fairer, greener Britain may just be ours.
