Hanna's freelance journalism was noticed by The Sunday Times editor Harold Evans, who offered him a job as an industrial relations correspondent. He embraced his new career with an enthusiasm that irritated some of his less committed colleagues. He was recruited by the BBC Current Affairs department in 1973 and became well known for his Newsnight coverage of by-elections. Fellow journalist Andrew Marr said his filmed reports were "a new kind of political reporting, much copied and never rivalled, which ended forever the era when parliamentary by-elections were obscure and largely unreported contests". His third campaign was spent doggedly pursuing candidates with difficult questions. Very few escaped unscathed. At Darlington in March 1983, Hanna's broadcasts helped to destroy the campaign of SDP candidate Tony Cook, who had been the early favourite to win. In 1984, Hanna's impartiality came into question when he failed to disguise his support for tactical voting in some reports on the Chesterfield by-election of that year. The Labour candidate, Tony Benn, accused him of acting as the SDP candidate. During the Greenwich by-election of February 1987, he publicly accused Angela Rumbold, a Conservative Minister, of being a liar. Rumbold had cross-examined him over the alleged impartiality of a public opinion poll which showed the SDP candidate closing on the Labour candidate.
Later career
Such was Hanna's identification with by-elections that in 1987 he was a guest star in Blackadder the Third, reporting on S. Baldrick's victory at the rotten borough of Dunny-on-the-Wold in the episode "Dish and Dishonesty". By this time, however, Hanna had left the BBC to set up his own freelance production company which specialised in trade union issues and mainly worked for the public service television station Channel 4. He also co-presented A Week in Politics for the channel from 1989 until his death. He was an active broadcaster on BBC Radio 5 Live from 1994. From 1996 he presented Medium Wave on BBC Radio 4 and also hosted two series of the panel game Cross Questioned. His media company gave public relations advice to several local authorities on presentation. Hanna was an active trade unionist in the National Union of Journalists. He led a strike at the BBC in 1985 when the Governors, bowing to Government pressure, suppressed a documentary called Real Lives: At the Edge of the Union which covered the home life of Martin McGuinness of Sinn Féin and Gregory Campbell of the Democratic Unionist Party.
Personal life
Hanna married Joan in 1975. They had two daughters. He died in 1997 of a heart attack, at the age of 57.
