The Bristol businessman appears to meet a man since convicted of her murder at a South African hotel. Mr Dewani denies any involvement in her death.
The High Court has temporarily halted British businessman Shrien Dewani's extradition to South Africa on mental health grounds.
Shrien Dewani, accused of arranging the murder of his wife on their honeymoon, is due to find out whether he is due to be extradited later.
CCTV footage which allegedly shows Shrien Dewani paying a taxi driver for organising his wife's death is to be shown on television tonight.
