Frankie Boyle, the Scottish comedian known for his controversial wise-cracks has gone on hunger strike.

He’s doing so to highlight the case of Shaker Aamer – the last British detainee in Guantánamo Bay. Boyle has previously awarded a £50,000 compensation payout from a defamation case against the Mirror newspaper to highlight Aamer’s case.

Clive Stafford Smith, who represents Aamer had gone on hunger strike in solidarity with his client and Boyle tweeted on Wednesday night:

 “Taking up the hunger strike by proxy for Shaker Aamer tomorrow.

Congratulations to the bold @CliveSSmith after 7 days. I’ll see how it goes.”

Once the hunger strike was underway he continued to update followers tweeting late last night:

“Day 2 of hunger strike feels a bit like being drunk. Feel pretty good, but no doubt I’ll wake up to find myself in bathroom eating soap.”

Keeping followers updated via twitter, the hunger strike hasn’t inhibited his caustic humour

Shaker Aamer has been on hunger strike in Guantanamo Bay for over 150 days. According to the ‘Stand For Justice’ website, people from around the world have promised around 1200 days hunger striking on the prisoners’ behalf.

Shaker Aamer was arrested in Afghanistan in 2001 and has been held at the prison in Guantanamo Bay, without charge, since then. Stand for Justice – a campaign by Reprieve, which Stafford Smith represents, is calling for fair trials around the world.

Boyle is sticking to the Guantanamo diet – coffee, water, a teaspoon of honey and a vitamin pill. While many if not most of the prisoners in Guantanamo are innocent or have never been charged, it is difficult for international observers to get access to them. It is unclear how many if not all are on hunger strike and how many are being force-fed.
