The Muslim wife of a convicted terrorist prosecuted after refusing to submit to a police airport interrogation has lost a human rights fight in the Supreme Court.

Sylvie Beghal - whose husband Djamel Beghal was jailed in France - claimed that her rights were violated when she was stopped by police and questioned under anti-terrorism legislation following her arrival at East Midlands Airport in 2011.

Five Supreme Court justices analysed her case at a hearing in London in November and ruled against her today.

Mrs Beghal, who is French, had already lost a fight in the High Court.

Three judges had ruled against her in August 2013 - following a hearing in the High Court in London.

But they had suggested that there might be ''room for improvement'' to anti-terror legislation which gave police the power to ''stop, question and detain'' people entering or leaving the UK.

Mrs Beghal's lawyers had said the case was the first in which the High Court had considered whether stop and question powers granted under Schedule 7 of the 2000 Terrorism Act were compatible with ''fundamental'' human rights.

Lawyers have explained how Mrs Beghal had arrived back in England after visiting her husband with her three children when she was stopped.

She was not ''suspected'' of being a terrorist but police said they needed to speak to her regarding ''possible involvement'' in terrorism.

Mrs Beghal argued that the process of stopping and questioning ''without reasonable suspicion'' breached the European Convention on Human Rights.

Supreme Court justices heard that Mrs Beghal had appeared before magistrates in Leicester and been convicted of failing to comply with a duty to answer questions.
