A parliamentary inquiry into the Libor fixing scandal, which was contentiously pushed through the House of Commons by the coalition government yesterday, may undermine a criminal investigation into the Libor scandal, according to lawyers.

MPs yesterday voted through the UK coalition government's plan to hold an inquiry to be led by Andrew Tyrie, the chair of the Treasury Select Committee. They approved the measure by 330 votes to 226, while also voting against the opposition Labour Party's rival proposal to establish a judge-led investigation, by 320 votes to 239.
