The most ironic tweet you will see on #WorldBookDay

This is how the Ministry of Justice marked World Book Day on Twitter.

As many of the people who replied pointed out, it was an interesting decision to highlight prisoner reading skills given the recent High Court ruling to lift the department's ban on sending prisoners books. It's also missing an apostrophe after the word prisoners.

The crackdown was imposed by Justice Secretary Chris Grayling in 2013 as part of attempts to make it more difficult to smuggle contraband into prisons. However it was described as overly punitive by the Howard league for Penal Reform and several prominent writers condemned the scheme.

The policy even faced opposition within the Ministry of Justice, with minister Simon Hughes telling the Independent it was the "wrong message". "It is totemic. We want education in prison. We want people to know that from the moment people will go in they will get help and rehabilitation so they don’t end up being a burden on the state again and don’t come back.”
