Seam bowler Roger Binny, who played in the final, recalls India's greatest triumph.
Did your supporters or the team hold out much hope of winning the World Cup in 1983?
Considering our performances in the last two World Cups people just expected us to go and have another World Cup and come back.
As a team we were looking to better that and come back with some sort of pride by winning a few more games.
Why did India pick medium pace seam bowlers rather than rely on their traditional strength of spin?
Former players like Bishan Bedi, who had played cricket in England, were on the selection committee.
Instead of going along with the spin tactics of the past, they picked bowlers who would suit English conditions. That was one of the reasons that we did perform well.
Was there any point in the campaign that you thought you could do better than before?
What really kicked us off was beating the West Indies in the first match of the tour. That was really a morale booster for our team.
Australia thrashed you by 162 runs in a group game. Did that raise doubts in your minds?
It was a good thing that we lost that game because we were getting a bit over-confident after beating a team like the West Indies.
How did you beat the hosts England in the semi-final?
We basically went out and played it tough. We didn't really think that because England were at home they had the advantage over us.
How confident were you going into the final against the favourites?
At that point in time there was a lot of pressure built up on us because we had gone this far. The team was really doing well and we had to carry on with the good work.
Our captain Kapil Dev said: 'We have reached this far and we have just one more game. Let's give it a good shot and try our level best.' And it worked for us.
How did India win after scoring just 183 batting first?
After we got out we really thought that we had come this far and thrown everything away.
But in the lunch break the players started to try to boost the others up a bit because everybody looked down and out.
The senior players said: 'We have to do it. We can't go back having lost the game.'
And that lifted the players and everything started falling into place. We got Gordon Greenidge out early, and they kept tumbling one after the other.
At what point in the final did you think you were going to win?
It was at the wicket of Viv Richards, when Kapil caught him off Madan Lal. He was the main threat and when that wicket fell everybody started believing that we could do it.
How did people react to the win in India?
It was really hysterical and you had to be there to believe it. People were lining the streets, throwing money, flowers and greetings into our bus. This World Cup really changed the face of Indian cricket.
