A guest was reduced to tears on Antiques Roadshow in Glasgow after learning the value of his father's rare World War II medal. 

The most recent episode of the BBC series was filmed at the city's Pollok Park which Charanjit Sangha attended.

He had with him a medal that was given to his father, Sikh soldier Naik Gian Singh, for his bravery in the Burma campaign in 1945. 

Glasgow Times:

But he admitted to expert Mark Smith that he had very little knowledge of his father's actions that led to him being awarded the most prestigious accolade for the British armed forces, the Victoria Cross. 

Charanjit said: "My dad never talked to us about the story. He used to get emotional whenever he talked about it. Obviously, he lost a lot of his friends in that battle.”

Mark then explained that he had found out about Naik's brave efforts in a book he had come across. 

He said: "Firing his Tommy gun and throwing grenades, Naik Gian Singh made two lone charges against the Japanese in Burma... it was essential that the enemy be dislodged from this area and when a Punjab platoon from a nearby village came under very heavy fire Naik Gian Singh ordered his machine gunners to cover him as he rushed the enemy foxholes.

“Our tanks had now moved up and come under fire but Naik Gian Singh, who had sustained several wounds, again rushed forward and annihilated the Japanese anti-tank gun crew capturing the weapon single-handed.

"He then led his section in clearing all enemy positions.

"Wow, I know these things happen really in the heat of the moment but that still takes some bravery to do that.

"To be that involved in the battle and to just keep going, even though he's wounded, is absolutely incredible."

Mark then explained that the Victoria Cross, introduced by Queen Victoria in 1856, was awarded to fewer than 1400 people.

Glasgow Times:

It was deliberately made of bronze as Her Majesty did not want it to be made of something precious as it is "about the deed, not the medal". 

Charanjit was taken aback when Mark revealed that its value was an incredible £250,000. 

He responded: "Even if it's worth £2 million, £10 million, we won't part with it. No way.

"It's amazing. I never thought it would be worth that much. I was in tears actually, I was crying."

Glasgow Times:

Mark added: "I can understand that. They are some of the most iconic things that we have in this country for our military, all across the world.

"And I will tell you now that meeting your dad and his medals today has been a true honour. Thank you so much."

When asked what he planned to do with the medals, Charanjit replied: "The medals will be going straight to the bank [for security].

"Then I think we as a family will collectively decide they should go to a museum so people can see and appreciate what my father did in the Second World War."
