With more than 16 million views on TikTok, Mr Osman has spent years working on his act, named Donald Trumped.
Despite having a southern English accent, the comedian seems to imitate Trump’s voice with ease.
“The first thing you’ve got to do is get the wig – and you’ve got to get it right,” he said.
The impressionist wears a bespoke hairpiece created by wig designers, which is regularly re-styled by a hairdresser.
Next is perfecting the costume, in particular Trump’s suit and iconic crimson tie.
“The tie is about eight foot long,” he joked, adding his seamstress neighbour had made it especially for him.
But the most important part of being a Donald Trump impersonator, he said, was replicating his eyes and mouth.
“I have watched a lot of videos of Donald, believe me,” he added.
