Welsh-educated US soldier Bradley Manning has been sentenced to 35 years in prison.
Manning, 25, was convicted last month of espionage, theft and other charges in the biggest leak of classified information in American history.
But he was acquitted of aiding the enemy - the most serious of the charges against him.
Manning spent four years at Tasker Milward VC School in Haverfordwest.
A Welsh play about Bradley Manning, the American soldier who passed military secrets to WikiLeaks, has won an award for drama.
'The Radicalisation of Bradley Manning', produced by National Theatre Wales, has been given the first James Tait Black Prize for Drama.
Manning spent four years at school in Haverfordwest.
It was written by Tim Price, and charts his radicalisation from those teenage years in Wales to the present day.
Manning was convicted of espionage charges by a US military court last week, but acquitted of the most serious charge against him - aiding the enemy.
The £10,000 award is the first of a new drama category in Britain's oldest literary awards. It was launched last year by the University of Edinburgh.
Tim Price said: "I am thrilled to be recognised by such a prestigious award, and honoured to be chosen as winner from such a fantastic shortlist of plays - that it is the first time a category for drama has been added to the James Tait Black Prizes is even more exciting."
The play is currently being performed at Edinburgh Festival Fringe.
A play about Bradley Manning - the former Welsh school boy at the centre of the Wikileaks controversy - is being premiered at his old school in Pembrokeshire tonight.
Manning has been accused of passing on hundreds of thousands of secret US government emails to the organisation that published them on the Internet.
The drama depicts how Manning went from life as a teenager in Haverfordwest to an Amercan prison where he is currently awaiting court martial.
