Punjabi language
In India, Punjabi is one of the 22 scheduled languages of India. It is the first official language of the Indian State of Punjab. Punjabi also has second language official status in Delhi along with Urdu, and in Haryana. 
In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect. Majhi is spoken in the heart of Punjab in the region of Majha, which spans Lahore, Amritsar, Gurdaspur, Kasur, Tarn Taran, Faisalabad, Nankana Sahib, Pathankot, Okara, Pakpattan, Sahiwal, Narowal, Sheikhupura, Sialkot, Chiniot, Gujranwala and Gujrat and in Mandi Bahauddin(97’/.) districts.
British Pakistanis
As the majority of Pakistanis in Britain are from Azad Kashmir and Punjab, some common languages spoken amongst Pakistanis in Britain are Punjabi, Potohari, Mirpuri and Hindko, which are closely related dialects of Punjabi. Other Punjabi dialects are also spoken in Britain, making Punjabi the third-most commonly spoken language. Other significant Pakistani languages spoken include Pashto, Saraiki, Sindhi, Balochi and a minority of others. The number of speakers of such languages (as a primary language) in the United Kingdom, based on an Ethnologue report, are shown below. Some of these languages are not only spoken by British Pakistanis, but also by other groups such as British Indians, British Afghans or British Iranians; these are indicated by asterisks.
