Two Star Trek fans have tied the knot in what is thought to be the UK's first Klingon wedding.
Josefin Sockertopp, 23, and Sonnie Gustavsson, 29, travelled from Sweden to London to exchange their vows at the first official Star Trek convention in Britain for more than 10 years.
They married at east London's ExCel Centre in full Klingon costume, to the sound of a drum.
Ms Sockertopp said it was a "once in a lifetime" occasion.
The couple exchanged vows, swearing to unite against all their opponents.
He concluded the proceedings with a Klingon cry which translates as life, honour, success.
Mr Gustavsson said: "I've been a fan of Star Trek since I was little.
"The Klingons are strong characters and they bond together. The ceremony was really fun."
His bride said she had to be persuaded to have a Klingon wedding but did not regret it.
"I hadn't seen Star Trek until I met him. He introduced me to it and it was really good," she said.
"The ceremony was his idea. I thought about it a lot and then I said 'let's do it'.
"It's a once in a life time thing."
