But now he has made a dramatic comeback.In the 1990s he was one of the Republicans who led the impeachment proceedings against President Bill Clinton for perjury over his affair with White House intern Monica Lewinsky.

She hears of similarities between Gingrich and Clinton: both had difficult relationships with their step-fathers, dominating mothers, and both wanted to be transformational figures. But Gingrich appears to lack Clinton's personal charm.Gingrich is both attacked and admired as an ideological politician, although some say he is driven by pragmatism and has an acute sense of what will play well with his supporters.With a controversial past - he was fined $300,000 for ethics breaches in Congress - how has he turned things round? Who is the real Newt Gingrich, and would he make a good president? Producers: Ben Crighton and Arlene Gregorius.

Claire Bolderson profiles Lord Justice Leveson, the judge who is leading the public inquiry into the phone hacking scandal and relationships between politicians, journalists and police officers. Brian Leveson was born and brought up in Liverpool and worked there, as a young barrister, for a number of years before becoming a QC. His later career involved some of the biggest commercial trials of the time - among them BCCI, Polly Peck and Barings. He also prosecuted Ken Dodd on behalf of the Inland Revenue and, in a rare setback, he lost the case. And he's turned his hand to the criminal bar and prosecuted one of the UK's most infamous serial killers - Rosemary West. If he handles the public inquiry into phone hacking successfully, many believe he will be one step closer to the ultimate legal prize - the position of Lord Chief Justice.
