“We will fund any sport where we think there is a realistic chance of a medal in Rio or in the 2020 Games”
Sports like handball and volleyball, which relied on host-nation places to compete in London, could be affected.
"There's no point funding sports that are not going to qualify," said sports minister Hugh Robertson.
The policy is known as
Supporters say it is the fairest and most accountable way of channelling public finances into developing elite level athletes for competition.
Critics, however, insist that investment is needed to develop Britain's less popular sports to allow Britain to compete at international level.
"We will fund any sport where we think there is a realistic chance of a medal in Rio or in the 2020 Games. The base cutoff is if a sport does not qualify for an Olympics, that is very important," clarified Robertson.

Baroness Sue Campbell, chair of UK Sport, said: "Investing in sport in an expensive business - world class success is expensive. We are investing the viewers' money, whether its coming from the government or Lottery.
"To invest large amounts of public money in people who quite frankly aren't going to get there is not good investment."
