During his career spanning nearly five decades, Khan has established himself as one of the most popular Bollywood actors, with a large following in India and abroad, especially in China.

In 2015, Khan, a Muslim, made headlines for saying there was a growing "intolerance" in India.

He drew criticism from the ruling BJP party but Khan said that neither he nor Rao, a Hindu, had any intention of leaving the country

He said that the people who had called him "anti-national" and shouted "obscenities at me for speaking my heart out, it saddens me to say you are only proving my point".

Khan had previously been married to Reena Dutta, with whom he has two children.
