Tom Daley's husband Dustin Lance Black has revealed that he recently suffered a "serious head injury".

The 48-year-old - an Oscar-winning screenwriter for the film Milk - told followers on Instagram that he had been ordered to rest by doctors following the injury as he begins a lengthy recovery process.

He wrote: "So I vanished for a while... A month ago I sustained a serious head injury that put me out of commission. Showing little improvement, my doctors ordered me to shut off my brain in hopes of it healing.

"This has been a challenging, frightening time for a creative type who depends on what's in his skull to work, care and love. And now I understand the road back will be long.

"But this week my sweet, over the top husband took us to the Greek Islands to make me shut off. I can already feel this trip is a step in the right direction, and I finally feel safe sharing a bit again.

"Thank you for all of your love and patience. More to come. Promise."

Prior to his injury Black, who married Daley in 2017, had been working on the script for Rustin, a new movie about '60s gay civil rights activist Bayard Rustin.
