Prime Minister Malcolm Turnbull never misses an opportunity to take a selfie with one of the world’s most influential leaders.

During a lengthy one-one-one meeting with Indian Prime Minister Narendra Modi on Monday, the two travelled along the New Delhi metro to see one of the city’s temples.

Mr Turnbull and his Indian counterpart took a break out of their formal talks on energy, education and trade for short train ride and brief tour of the Akshardham temple.

It was a media frenzy, as Indian media reported crowds flooded the Mandi House station to get a glimpse of their leader, chanting “Modi, Modi, Modi”.

Tight security and a plethora of officers were required to keep the crowds at bay as the two prime ministers boarded the Blue Line train.

It was an opportunity the Australian PM couldn’t pass up, adding to his collection of selfies with other leaders.

However, the spontaneous photo came with a price, as Labor Senator Murray Watt slammed the prime minister on public transport.

“Hi PM @narendramodi. Can you have a word with @TurnbullMalcolm about importance of building train lines, as well as taking selfies on them?” he wrote.

Mr Turnbull has previously snapped himself alongside Canadian Prime Minister Justin Trudeau and other leaders at G20 summits, as well as one with Indonesian President Joko Widodo during a tour of a Jakarta market in 2015.

His most famous selfie came with former US President Barack Obama in Peru last November, to mark their final meeting during Obama’s presidency.

Mr Turnbull re-iterated at a speech on India-Australia education links on Monday night, he and Mr Modi are working on fixing their nations’ disparities on trade.

“That is a very important prime-ministerial commitment to getting on with it and dealing with it and identifying where the parties are close, where they’re apart,” Mr Turnbull said.

“The process needed some energy, and it has been re-energised today.”

Mr Turnbull praised Mr Modi for acknowledging the slow progress on a free-trade agreement between the two nations, and that the talks should be resuscitated.

“We have agreed to direct our chief negotiators to meet as soon as possible,” Mr Turnbull said, describing the development as an “important prime-ministerial commitment to getting on with it”.

Neither side has committed to a timeframe for concluding a deal.

Mr Turnbull is no stranger to selfies on home soil, either.
