(Adds investigation over Hyundai Motor para 5-9)
SEOUL, Nov 20 (Reuters) - South Korean Prime Minister Goh Kun said on Thursday the government would try to wrap up an investigation into a political funding scandal soon to minimise impact on the economy, YTN television said.
Prosecutors have launched a wide-ranging probe into links between South Korea's top family-run conglomerates, or chaebol, politicians and bureaucrats.
Investigations at firms affiliated with LG Group, the country's second-biggest conglomerate, have rattled markets.
"We'll try to wind up the probe as swiftly as possible because the probe can have a negative impact on the economy," YTN quoted Goh as telling the parliament's budget committee.
Prosecutors stormed LG Home Shopping Co , a unit of LG Group [LUGG.UL], on Tuesday after barring 20 executives of LG and other business groups from the leaving the country during the investigation.
Yonhap News Agency reported prosecutors were investigating the country's top auto maker, Hyundai Motor Corp , over possible illegal political funding and that chief executive Kim Dong-jin would be summoned soon for questioning.
The report quoted prosecutors as saying Hyundai made contributions to the Grand National Party during the presidential election last year in excess of the legal limit.
Hyundai Motor has denied any wrongdoing.
"All money that we contributed to political parties was within the legal boundary and proper accounting procedures were followed according to laws and principles," Hyundai spokesman Park Sang-woo said by telephone.
Prosecution officials were not available for comment.
The benchmark Korea Composite Stock Price Index (KOSPI) ended down 0.3 percent on Thursday after a more than three percent fall the previous day as financial stocks faltered.
