Should Harper Lee’s Go Set a Watchman have been published?

After much razzmatazz, worldwide publicity and midnight openings by bookshops, this week saw the publication of Harper Lee's Go Set a Watchman.

It went on sale more than fifty years after To Kill a Mockingbird was published. While that is regarded as one of the finest novels of the twentieth century, the merits of this new novel are being questioned.

For this week's vlog, our Arts Editor, Will Gompertz, went to a library at the University of Westminster in London to ponder whether Go Set a Watchman should have been published at all.
