Taking a cue from Indian authorities decision on Valerie Trierweiler, an Indian court might take this as precedence in considering a ‘girlfriend’ as the ‘wife’ of a person, considering the ‘Protocol’ of nation defining its Governments opinion on a certain matter of precedence and hence ‘legal’.

In stark contrast to the treatment meted out to ‘Sarkosis’ girlfriend ‘Carlo Bruni’ who was restricted to her suite during the former French President’s visit probable pressure from the new French President should have made India buckle under pressure in accepting a ‘girlfriend’ as wife.

French president Francois Hollande’s girlfriend Valerie Trierweiler will be treated as his ‘honorary wife’ on a state visit to India to avoid protocol problems in the conservative country.

Hardline religious leaders had demanded that Mr Hollande travel alone to India on the trip later this month because he and his partner are ‘living in sin’.

But the Indian government has now agreed to relax their diplomatic rules and treat the 47-year-old divorcee Valerie Trierweiler as his legal wife.

The Asian Age newspaper reported: ‘Every honour reserved for the wives of heads of state will be afforded to Ms Trierweiler when she visits.

‘She will get the full Indian red carpet treatment.’

The decision to welcome the French First Lady Valerie Trierweiler as the president’s wife on February 14 is a major U-turn on the Indian’s treatment of Carla Bruni five years ago.

She was forced to loiter in her Delhi hotel – where she had her own room – while boyfriend and president Nicolas Sarkozy attended a string of official functions.

Bruni was not even allowed to accompany Sarkozy at all when he visited the strict Muslim kingdon of Saudi Arabia, where unmarried couples are not allowed to be alone together.

Ms Trierweiler was left seething last year on a visit to Washington DC when American journalists repeatedly quizzed her about her status at a G8 summit.

Ms Trierweiler has also told the French media that she and Mr Hollande – who have been together for five years – ‘have no current plans to marry’.

She said: ‘I’m not so sure it will pose a diplomatic problem – except perhaps on a visit to the Pope.
