Referring to his speech at the BBC’s Cardiff headquarters last week, he said: “As I said last week, we have to develop our ideas for both. And it must be right that the BBC has one person to lead it through both stages.
“Over the next six months my priority, as always, will be to champion this great organisation and continue to direct our reinvention.
“There’s so much we can do to transform the creative industries around the UK still further and to project this country’s talent and ideas to the world.”
He said he feels he is “leaving the BBC in a much stronger place than when I joined”, adding: “It feels a very different organisation – more innovative; more open; more inclusive; more efficient; more commercially aware.
“And a BBC that’s on cracking creative form. You all have my thanks and admiration for the part you’ve played in that success.”
Lord Hall, 68, also praised the values of the BBC, saying the corporation must continue to “champion the nation’s creativity at home and abroad, and help play its part in bringing the UK together”.
He added: “In an era of fake news, we remain the gold standard of impartiality and truth. What the BBC is, and what it stands for, is precious for this country. We ignore that at our peril.”
