South Korea chooses new president with inequality key concern******

AFP

A woman casts her vote in the presidential election at a polling station in Seoul on March 9.

South Koreans were at the polls electing a new president on Wednesday with economic inequality a top concern, especially among young swing voters.

Polling booths opened at 6am (9pm GMT) and record early voting indicates turnout will be high after a campaign dominated by mud-slinging between liberal Lee Jae-myung and conservative Yoon Suk-yeol.

The pair, who are both so unpopular local media have branded it the "election of the unfavorable," have been neck-and-neck in the polls for months. Some 90 percent of the electorate supports one or the other.

In South Korea, presidents serve just a single term of five years, and every living former leader has been jailed for corruption after leaving office.

Yoon has already threatened to investigate outgoing President Moon Jae-in, citing unspecified "irregularities."

The two parties are ideologically poles apart, and analysts say the key question is whether voters will kick out Moon's dovish Democratic Party and usher in a new hawkish, fiscally conservative regime under opposition People Power Party's Yoon.

"What the country needs right now is change," 71-year-old Hong Sung-cheon told AFP at a polling station in southern Seoul. "We cannot go on like this."

However, younger swing voters are likely to prove decisive, analysts say, and their top concerns are skyrocketing house prices in the capital Seoul, domestic inequality and stubborn youth unemployment.

"Young voters are not loyal to any particular political party and thus can't be defined by liberal-conservative ideology," said Shin Yul, political science professor at Myongji University.

"Turnouts and choices by those in their 20s will have a significant bearing on the outcome," Shin added.

Both leading candidates have promised to build millions of new homes, although the left-leaning Lee relies more on public housing and conservative Yoon on market-led solutions to the crisis.

"I'm really worried about housing prices in Seoul and I hope the new president will focus on making people's lives easier and better," Park Ki-tae, 38, said.

Newcastle United manager Bruce leaves club******

LONDON, Oct. 20 (Xinhua) -- Newcastle United manager Steve Bruce has left his position by mutual consent, confirmed the English Premier League club on Wednesday.

Earlier this month, a Saudi-led consortium completed the 305-million-pound (about 420 million U.S. dollars) takeover of the club and Bruce's future has been doomed as the Magpies haven't won any game in the Premier League this season.

During his charge of the team in more than two years, Bruce led the Magpies to 13th and 12th-place finishes in the Premier League.

"Newcastle United would like to place on record its gratitude to Steve for his contribution and wishes him well for the future," read the statement released by the club.

"I am grateful to everyone connected with Newcastle United for the opportunity to manage this unique football club," said Bruce.

"This is a club with incredible support, and I hope the new owners can take it forward to where we all want it to be. I wish everyone the very best of luck for the rest of this season and beyond," added the 60-year-old English.

Newcastle United lost to Tottenham Hotspur 3-2 on Sunday, collecting only three points from eight Premier League matches so far.

The club has appointed assistant coach Graeme Jones to lead the team on an interim basis, starting with Saturday's trip to Crystal Palace.

"The process of recruiting a new head coach is under way and an appointment will be announced in due course," said the club. Enditem

The fire broke out shortly after the clinic opened forbusiness at 10am (1am GMT) and it was largely extinguishedwithin 30 minutes, public broadcaster NHK reported.。

Video from NHK showed smoke pouring out of the windows ofthe fourth floor, where the clinic was located, as well as theroof of the multi-story office building. Footage later showedthe windows, blackened and charred.。

"When I looked outside I saw orange flames in thefourth-floor window of the building. A woman was waving herhands for help from the sixth-floor window," a 36-year-old womanwho works at a company nearby told Kyodo.。

Located in a shopping and entertainment district not farfrom Osaka's main train station, the building also houses abeauty salon, a clothes shop and an English-language school, NHKsaid.。

The father of a doctor who ran the clinic was not able toreach his son by mobile phone, he told the Yomiuri newspaper.。

"Around noon I heard there was news of a fire on televisionand was surprised. My wife went to the site but we still don'tknow what's going on. I can't get through to my son's phone."
