BBC Radio 4 today started broadcasting a series of daily programmes in which the Canadian historian Prof. Margaret MacMillan gives a five minute summary of the news from each day from 27 June 1914 up until the outbreak of the First World War.
Each programme is broadcast at 4:55 pm on BBC Radio 4, and all will be available on the I-Player from this link once they have been broadcast. Radio programmes normally stay on the I-Player indefinitely, and I think that, unlike TV ones, there are no geographical restrictions on listening to them.
