Too much rests on the future of PSB for us to duck this fiendishly challenging riddle.

In a rather weary moment, one contact said to me that the PSB debate was broadcasting's “Europe”. For politicians, Europe is an issue of critical significance but one burdened by policy and reviews and a concern that it will never quite get sorted. For the broadcast sector, PSB can sometimes follow much the same line.

Which is why, amid Ofcom's statement, Andy Burnham's Oxford speech and Stephen Carter's upcoming Digital Britain report, it is real-life events that bring the importance of the debate into sharp relief.

The rights and wrongs of the BBC's decision not to air the DEC Gaza appeal have been much debated. In terms of broadcasting, some of the issues that the decision has thrown up - such as impartiality, editorial independence and the role of the BBC - underline, if it were needed, the massive power of the UK broadcasting sector. They are also crucial PSB issues.

PSB is at the heart of some of the best programming in Britain. News - how it is reported, and how it is perceived to be reported - is at the centre of that. In our interview with Ed Richards, the Ofcom chief executive emphasises the need for plurality in PSB provision. He supports a proposed second PSB institution as the preferred way of achieving this.

While plurality can be seen as a policy term, the impact of what it means for viewers cannot be underestimated. Plurality of PSB content provision should enhance choice and help keep editorial standards high. The PSB argument matters and the debate is worth having.
