David Gallacher, 37, is accused of assaulting the Muslim mum-to-be by kicking her in the stomach
He also allegedly attacked a man who tried to intervene during the incident near a Co-op store in Milton Keynes, Bucks., last August.
The unnamed Somalian woman, who is a mum-of-four, was forced to flee her home in fear as a result of the assault. She had not known she was expecting twins until medics told her she had lost them following the assault.
Her 40-year-old husband has had to give up his job as a taxi driver to stay home and reassure his traumatised wife.
