Asking Prime Minister Narendra Modi to take a cue from UK government's warning that migrants on spousal visas who fail to speak English may face deportation, Shiv Sena on Wednesday said madrassas in India should be barred from using Urdu and Arabic as medium of instruction and they should be replaced with English and Hindi.

The ruling ally also took a swipe at PM and his ministerial colleagues, saying while they might succeed in getting investments into the country by touring other nations, from where would the courage come to fight enemies within the country.
