Set between 1972 and 1990 with a brief spell in 1940, The Gang of Three is a 90 minute delight.

Robert Khan and Tom Salinsky's new play follows Labour cabinet big beasts Roy Jenkins, Denis Healey and Anthony Crosland in their behind-the-scenes scheming for the top job.

The action focuses in on 1976 when Harold Wilson announced he was resigning as prime minister and the trio plotted in secret over who should succeed.

Of course, in the end, their rivalry led to James Callaghan and 18 years of Tory rule in this witty tale of their feuding.

And although much of the action takes place half a century ago, it couldn't be more relevant as those vying for power complain about the party's political fringe disuniting their core base and electability.

The Gang of Three is very funny, but we'd go as far as saying that the performances are even better than the script.

In particular, Hywel Morgan and Colin Tierney's takes on Jenkins and Healey are a delight to behold as Alan Cox's Tony Crosland navigates between his two cartoonish counterparts. A small play but a big treat.

The Gang of Three is performed at King's Head Theatre until June 1 and tickets can be purchased .
