At such an unhappy time, there might be some solace to Egypt's protestors in knowing that they were the best versions of themselves for a luminous moment that inspired the planet with the idea of what it could be, and that history will record the protestors as infinitely greater and braver than the people that ruled them before and, unfortunately, since.
As UK citizens it's important we stand in solidarity with CAAT's legal action, lending our signatures to their online petition, and lobbying our MPs to take a stand in the commons. It is clear, now more than ever, that the UK has to review this destructive trade relationship. It's time for the UK to #StopArmingSaudi.
I started out feeling scared - of the foreboding mountainous landscape and the dark drive from the airport through it; of the inevitable street hassle one gets as a European walking past Egyptian shops.

What impressive dexterity our prime minister is demonstrating. In February 2011, there he was, grandstanding in Tahrir Square, celebrating with Egypt's pro-democracy activists the overthrow of the country's former leader, Hosni Mubarak.
