Prosecutors said Friday they will summon an elder brother of former President Lee Myung-bak next week for questioning over alleged influence peddling involving South Korea's top steelmaker POSCO.
  

Lee Sang-deuk, the former six-term lawmaker, is set to appear before the Seoul Central District Prosecutors' Office on Monday, they said.
  

The elder Lee is suspected of peddling his influence to the authorities for POSCO in return for landing business contracts for TM Tech, a local company owned by his close acquaintance, known only by his surname Park.
  

 Prosecutors suspect the elder Lee could have gained personal profits from dividends Park received worth about 2 billion won ($1.6 million) from TM Tech. Park is a major shareholder of TM Tech.
  

The planned summons is the latest in a series of investigations into suspicious deals and alleged slush funds created at POSCO from 2009 to 2014. (Yonhap)
