PARIS, July 28 (Reuters) - French defence and electronics group Thales is set to announce a contract worth about one billion euros ($1.11 billion) to modernise four London Underground lines, French news website La Tribune reported on Tuesday.
Talks have been underway for 18 months with the London Underground since it ended a contract with Canadian group Bombardier in 2013, La Tribune said.
Thales declined to comment when contacted by Reuters about the report.
