Lawyers representing two freelance Channel 4 journalists who are being held by police in Bangladesh are in court again on Sunday amid a continuing row over access to their clients.

Zaiba Malik and Bruno Sorrentino were arrested last week for entering the country to make a feature on Islamic extremism without having journalist visas.

Police are expected to ask a magistrate's court in Dhaka for Bruno Sorrentino and Zaiba Malik to be remanded in custody for further questioning

The defence team for the two Channel 4 journalists is making two key arguments in Dhaka's High Court.

They are demanding the right to consult with their clients, which they say has so far been denied despite an earlier court ruling in their favour.

They are also asking the court to guarantee that the two journalists will be looked after properly while in custody and provided with regular food and water.

Bail to be opposed

They will argue that their continuing detention in police custody is a breach of their basic human rights.

Later on Sunday police are expected to ask a magistrate's court in Dhaka for Bruno Sorrentino and Zaiba Malik to be remanded in custody for further questioning.

Their application will be opposed by the defence, who will submit that they should be immediately given bail.

The sensitivities surrounding this case mean that will be unlikely, although lawyers for the two journalists are optimistic they should be released and deported from Bangladesh before Christmas.
