More than 100 MPs and peers have written to the foreign secretary calling for "quick and decisive" action to secure the release of a Scottish Sikh man in prison in India.
Jagtar Singh Johal, from Dumbarton, was arrested in November 2017 in connection with terror-related offences.
He has not been convicted of any crime and in March was cleared in one of nine cases against him.
The Foreign Office said it remained committed to working for faster progress on the case.
Mr Johal's family and legal team had hoped India's Supreme Court would issue a ruling on Thursday on whether he would be granted bail but they say there was no decision and no timeframe for the matter to be resolved.
Mr Johal is accused of being a member of a terror group, the Khalistan Liberation Force (KLF), which has carried out attacks in the Punjab region.
