Is there a need of article here?

As you described it, yes you need an article.

No article if it is an ideology. It would be like: Why do you want Islam?

However if you asked, "Why do you want an Akhand Bharat state?" then an article is needed.

I should think that the rules of English grammar get a bit more complicated when you mix English and another language in the same sentence. Also I think that, in the context, the requirement for an article is not certain. Consider the 1950s Greek Cypriot desire for union with Greece ("Enosis"). One would have asked, "Why do you want Enosis?", not why do you want "an Enosis". One can desire a united India (as an ideal) or one can desire Akhand Bharat.

Oh! thank you all for your great replies and time. I appreciate it. Though I'm still not sure about it, but I sense the majority is for no article. I think I should go with no article. What say folks? What should I do? More replies are welcome by the way.

We can't say for sure if you need 'an', Razer, until we know the exact meaning you want to convey.

If you're saying a country, a unified state, then,

"Why do you want an Akhand Bharat?"

because it doesn't yet exist. It's like saying,

"Why do you want a fictitious state like Akhand Bharat?"

If this ideology exists and it is known by the name "Akhand Bharat", then there's no need for an article;

"Why do you want Akhand Bharat/socialism/communism/capitalism/etc?"

Thanks. Googled a bit on this topic, the more correct translation of "Akhand Bharat" would be "Undivided India". Some groups and people dream of a "Akhand Bharat". To one such person I wanted ask through e-mail "why do you want Akhand Bharat?"

Your reply has cleared all of my doubt. Thanks a ton. I shall use the word without any article because "undivided India" doesn't exist and merely a dream and an aim of some.
