At the age of 81, Caryl Churchill, Britain's greatest living playwright, is still going strong. Her latest is a typically imaginative quartet of short plays. Each of them is vividly distinct, being linguistically agile, theatrically pleasurable and emotionally dark, yet all are also united by the common theme of folk tales and strongly archetypal stories.

An all-girl rock group from the 1980s meet again, 30 years after an acrimonious break-up brought their shared stage career to an end … and the sparks fly as old resentments resurface and the bitterness of life’s blows emerges. Will their one-time all-girl solidarity overcome their pain and regrets? Will the show end with them back together, belting out their iconic anthem?

Are first ladies second-class citizens? Do they always have to stand behind their husbands? What are they really like as people? Questions such as these have inspired Irish playwright Nancy Harris to explore the relationship between two fictional first ladies, each of which bears an uncanny resemblance to a real-life figure. One is clearly based on Melania Trump, the other on Brigitte Trogneux, better known as Mrs Macron.

Earthiness, lyricism, fatalism, the undeniable force of passion, of ecstatic attraction, known as "duende": these are the familiar ingredients of Lorca's plays set in rural Spain. Blood Wedding, written in 1932, was the first, followed by Yerma two years later and The House of Bernarda Alba in 1936, the year of Lorca's murder by Nationalists. As a gay, left-wing artist - he was a poet and musician as well as a playwright - he was an obvious target.

Mother of Him was written a decade ago, but its most prescient moment happens in the first five minutes of Max Lindsay's production at the Park Theatre. Brenda Kapowitz (Tracy-Ann Oberman) presents a sheaf of papers to Robert (Simon Hepworth, excellent), a family friend who’s also her 17-year-old son’s lawyer. “Report cards, awards,” she explains.

The only novel by the Hungarian dramatist Ödön von Horváth, Youth Without God was written in exile after he fled Anschluss Vienna and published in 1938, shortly before his death.

The Permanent Way first roared its way into the national consciousness in 2003 when, after a triumphant opening in York, it toured the UK before transferring to the National Theatre.

Canadian playwright Hannah Moscovitch’s “refugee musical” – now there’s a phrase you don’t expect to write – is a treat. Harking back to the early 20th century pogroms of Eastern Europe, it’s darkly steeped in history, conveying the sorrows of leaving behind an old world as well as the slow, painful process of integration into a new one, in this case Canada.

The work isn't finished on Big, if this stage musical of the beloved 1988 Tom Hanks film is ever to, um, make it big. A Broadway flop in 1996 where it was among the last shows directed by the late, much-admired Englishman Mike Ockrent, the material finds a sweetness in its West End incarnation that eluded it Stateside.

Alexander Zeldin continues his devastating analysis of modern Britain in this culminating play of a (very loose) trilogy that started with 2014’s Beyond Caring, followed by LOVE two years after that.
