Controversial comedian Frankie Boyle has begun a hunger strike in a show of support for the last British convict being held in Guantanamo Bay.

The former Mock The Week host is attempting to highlight the plight of Shaker Aamer, who has been a prisoner at the camp since 2002.

He is aiming to go for a week without food in solidarity with Shaker – who has been on hunger strike since March.

Frankie has been keeping his Twitter followers updated on his progress as the week goes on.

He joked on day one: “Well Day 1 of hunger not too bad. But let’s remember who’s really suffering. My local pizza shop. I jest.”

The next day he added: “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.”

Frankie is following on from US lawyer Clive Stafford Smith, whose legal action charity Reprieve is seeking justice for Guantanamo convicts.

“One purpose of these symbolic actions is to provoke debate, to press President Obama to fulfill his post-election promise, and I suspect Frankie is better at doing that than I am,” he said.

Shaker, who grew up in Saudi Arabia before becoming a UK resident, has never been charged with any crime despite being held in the camp.
