Daily dispatches from Simon Reeve with these welcome repeats of a couple of his earlier travel series.

Today he goes behind the picture-postcard view of Greece in the first of a two-parter (the second part airs tomorrow) from last year, to discover how its people are doing in troubled economic times.

Simon learns about the dying art of sponge fishing, a once-booming industry for Aegean islanders, while on Lesbos he sees the extent of the migrant crisis as boatloads of Syrian refugees pour in from Turkey.

From Wednesday, there’s another chance to see Simon’s excellent three-part series on the Caribbean, first shown in 2015.
