In July 2013, a report commissioned by the BBC Trust found that the organisation had been slow to reflect widespread public concerns about immigration to the United Kingdom and shifts in public attitudes towards the European Union. The report, by Stuart Prebble, stated that Helen Boaden, the former director of BBC News, had said that when she arrived at the organisation, there had been a "deep liberal bias" in the handling of immigration issues. It also stated that, within the BBC, "the agenda of debate is probably too driven by the views of politicians" but that "overall the breadth of opinion reflected by the BBC on this subject is broad and impressive, and no persuasive evidence was found that significant areas of opinion are not given due weight today". It also stated that the BBC was "slow to give appropriate prominence to the growing weight of opinion opposing UK membership of the EU, but in more recent times has achieved a better balance".
