Philip Pullman has apologised for a tweet he sent early this morning and said that he doesn’t ”advocate hanging Boris Johnson”.

The His Dark Materials author previously tweeted: “When I hear the name ‘Boris Johnson’, for some reason the words ‘rope’ and ‘nearest lamp-post’ come to mind as well”.

Following criticism from many on Twitter, Pullman deleted the tweet and commented: “I’ve deleted a tweet which apparently upset a lot of people. I don’t advocate hanging Boris Johnson. I think that would be a very bad idea. Recent events have aroused my anger to the point where I temporarily lost my judgement. In the heat of the moment I made a tactical error.”

Blume has said she wrote the novel after one of her daughters asked her for “a story about two nice kids who have sex without either of them having to die”.

Best YA books for all ages The Fault in Our Stars, John Green Yes, one John Green book had to be included in this ranking. The 41-year-old author’s fourth solo book (he has co-written two) debuted in first position on the New York Times bestsellers list of children’s chapter books. Soon, the world swooned (and obsessed and cried) over the love story of 16-year-old Hazel, a teenager with thyroid cancer, and Augustus, an osteosarcoma survivor. The book generated so much chatter (and a 2014 film starring Shailene Woodley and Ansel Elgort) that it can he bard to remember what it was like to read it at the time of its release, when Green was only kind-of famous and the book hadn’t become a worldwide reference just yet. Forget about the chatter: The Fault in Our Stars is a beautiful, poetic book about love, loss and grief – the kind that may change you a little bit by the time you read its final sentence.

He had earlier tweeted: “For goodness’ sake. Of course I wasn’t advocating hanging the bastard. But rulers who try and do away with democratic parliaments come to bad ends. As I pointed out on Twitter some time ago, the axe and the block are still in working order.”

Pullman’s earlier tweet was met with criticism shortly after it was posted, with author Emma Kennedy suggesting that he take down the comment before he faces consequences.

She tweeted: “Philip, you’re my hero, but that tweet will be reported and you’ll be banned and that would be the absolute last thing we all need. So pause and perhaps think about deleting?”

Others have written of their intention to report the tweet, with one Twitter user copying in the Twitter handle of the Metropolitan Police over Pullman’s message.

“Threatening violence against MPs? Good job that’s never led to any bad consequences for anyone,” wrote one follower.

Another added: “I’m a big fan but this is a step too far. You may want to delete this.”

Steve Peers, professor of EU, Human Rights and World Trade Law at the University of Essex, tweeted to Pullman, “This is seriously OTT”.
