The Oscar-winning British actress with a soft spot for “progressive” and other assorted nutty causes is due to visit the island in July for the premiere of a film directed by her son, according to reports from Havana.
It will be her second visit to Cuba – the first was back in 1961.
In the intervening period, the woman who is often described as British "acting royalty", has become something of a celebrity socialist in her homeland, taking a prominent role in a range of issues that could best be pigeon-holed as well, fringe.
You know, predictable Left-wing causes such as attacking Israel, marching against the Iraq War, demanding that capitalist banks cancel all Third World debt, describing George W Bush as a war criminal ...
Along with her brother Corin, the actress even set up her own political party, although that turned out to be a less than successful enterprise.
Still, given Ms Redgrave has described the US base at Guantanamo Bay as a “concentration camp”, we have no doubt her impending visit to the Castro brothers' tropical paradise will most likely result in a truckload of officially-approved headlines in what passes for the Cuban media.
