LONDON, July 3 (Reuters) -

Rupert Murdoch-owned British tabloid newspaper The Sun

endorsed the Labour party and its leader Keir Starmer on

Wednesday, one day before a national election.

Britons will vote on Thursday in an election which opinion

polls say will bring Labour to power and end 14 years of

Conservative government.

"It's time for a change," the Sun said in an editorial

published online.

"The insurmountable problem faced by the (Conservatives) is

that - over the course of 14 often chaotic years - they have

become a divided rabble, more interested in fighting themselves

than running the country."

It added: "There are still plenty of concerns about

Labour ... But, by dragging his party back to the centre ground

of British politics for the first time since Tony Blair was in

No. 10, Sir Keir has won the right to take charge."

The paper

joins

the Financial Times and the Sunday Times in endorsing the

opposition Labour Party.

Among other newspapers, the Daily Mirror and the

Guardian have also endorsed Labour, while the Daily Mail and the

Daily Telegraph have backed the Conservatives. The Economist, a

pro-business weekly magazine, has thrown its weight behind

Labour.

The Sun is one of Britain's best selling newspapers and

boasts a record of backing winners in elections.

The tabloid, part of Rupert Murdoch's News Corp ( NWSA )

media empire, famously crowed "It was the Sun wot won it" in

1992, claiming its support had swayed 10 million readers to back

John Major's Conservatives to an unexpected election victory.

It switched its support to Labour before Blair led the party

to the first of three successive election victories in 1997.

In 2009, The Sun turned away from the Labour Party after

more than a decade of support and said it would support David

Cameron's Conservatives under the headline: "Labour's Lost It".

Labour lost the 2010 general election.

It has supported the Conservatives ever since.
