The winner of a transgender beauty pageant in the UK has had her crown taken away because organisers considered her to be "not transgender enough".

BBC documentary footage showing Jai Dara Latto, 22, working out in a gym wearing a T-shirt and shorts was enough to label her as a drag queen and not living fully as a woman.

Other video which emerged six months after September's pageant showed Latto wearing boxer shorts, the Scotsman reports.

"When Jai entered the competition, she said she was full time and she is not - she is a drag queen," pageant organiser Rachael Bailey said.

"Underwear is very important to transgender females - one of the first thing people do is change their underwear as it makes us feel like we are finally a woman."

The prize of $20,000 in surgical procedures in India has now been given to another contestant.

But Latto insists she is transgender and is now planning on having an operation in her native Scotland.

"Being transgender is not some exclusive club," she said.

"There are many of us in it and we are all different from one another."

Latto has now criticised the pageant as forcing transgender women into the female stereotype of long hair, tight clothes and lacy underwear.

"I am transgender. It seems to me that Rachael has based (her claims) on her subjective opinion from having viewed the documentary Miss Transgender, which is yet to be aired," she said.

"I gave consideration to sharing a letter from my doctor on my gender dysphoria but decided against it."

She says she is already taking hormones to become biologically female.
