Compared variously to Alan Ayckbourn, Alan Bennett and George Bernard Shaw,  Peter Briffa's writing style is characterised by pithy, acerbic, satirical dialogue, with blackly comic undertones. His plays explore the small psychological battles raging between seemingly good-natured, but often very damaged, delusional characters, who often know less about themselves than do the audience. These plays tend to follow the Aristotelian pattern of one set, in a short, or at least one clearly-delineated timeframe, with much of the worst, most extreme behaviour occurring offstage. If there is one consistent theme, it is of people given sudden, unexpected opportunities to change their lives. Chances that are usually, but not always, squandered.

Peter's first play, Night of the Fox was produced and directed by Sam Shammas in 1996 at the Lilian Baylis Theatre, Sadler’s Wells. It  was over fourteen years before Siren came calling.

In the interim Peter worked as a script reader for BBC Films, and became one of the first political bloggers to be signed up by the national press, writing opinion columns for the Times as well as other leading national websites. He even spent four years commentating on the reality TV show Big Brother for the News of the World on-line.

He was also the Programme Secretary for Player-Playwrights from 2008-2011. In 2010 with director Paul Blinkhorn he set up the Chilling Out Theatre Company, and his one act play Siren was a sell out at the Etcetera Theatre (Camden, London) as part of the Camden Fringe Festival.

A year later Country Life was produced by Player-Playwrights at the GBS theatre, RADA, again as part of the Camden Fringe, and was one of only two full length plays to premier in the festival. It later transferred to the Old Red Lion in Islington (London) for a three week run. It has since been recorded by the Wireless Theatre Company and was its most popular download for three successive months.

in 2017 Peter and Paul returned to the Camden Fringe with a one act play The Boot.

Peter was interviewed by Rhoda Koenig for the Islington Tribune in August 2011. He lives in Bow, East London with his wife and two sons, working as a hypnotherapist, specialising in phobias and anxiety.
