UK Sport unveiled their budget for the next four years today here at their headquarters in London.

A total investment of £345 million ($434 million/€411 million) will be made to 31 Olympic and Paralympic sports for the next Games - £2 million ($2.5 million/€2.3 million) less than a record £347 million ($436 million/€413 million) allocated in the run-up to Rio 2016.

Four Olympic sports have had their funding from UK Sport cut for the 2020 Games in Tokyo while wheelchair rugby was the only Paralympic sport stripped of its financial support.

Great Britain is currently ranked fifth in the world in wheelchair rugby and only lost to Australia, the Rio gold medallists, by two points in extra time in Brazil.

"This news is very disappointing and obviously not the news we wanted," said David Pond, chief executive of Great Britain Wheelchair Rugby.

"We have a talented and ambitious young squad who are developing well and who came very close in Rio.

"The severing of all funding for the national programme unfortunately puts a question mark over the future of the GB team."

A heavy cut also effects disability shooting, which has lost around £1 million ($1.25 million/€1.19 million) in funding.

Their previous investment of £3.4 million ($4.2 million/€4 million) has been cut to £2.4 million ($3 million/€2.8 million) following a disappointing Rio 2016 campaign.

Para swimming has also received a surprise cut after their impressive display secured Great Britain the most medals from a single sport in Rio.

Great Britain's Para-swimmers took home 47 medals, 32 of which were gold or silver, but have seen their investment reduced from £11.7 million ($14.7 million/€13.9 million) to just over £11 million ($13.8 million/€13.1 million).

Goalball UK, the governing body of the only Paralympic sport specifically designed for the blind and visually-impaired, has also expressed its disappointment at a lack of support for the elite development of its athletes in today’s UK Sport funding announcements.

Despite its most successful two years to date, with both the men and women’s teams achieving promotion to the top league of European competition, the sport will once again receive no financial support in the run-up to Tokyo 2020.

“We are shocked by the decision by UK Sport not to support either our men’s or women’s team," said Mike Reilly, chief executive of Goalball UK.

“As both teams recently won promotion to the Euro A division, Goalball UK were confident that UK Sport would recognise the strong progress and further potential of both teams over the last two years.

“Once again, team sports have been dealt a poor hand by UK Sport whose priorities seem to be in direct conflict with the Government’s ‘Towards an Active Nation’ strategy."

Today’s announcement has seen a rise in funding for most sports though, with wheelchair basketball receiving a significant increase as a result of their men’s bronze medal at Rio 2016.

The sport received a total investment of £5.3 million ($6.6 million/€6.3 million) during the Rio cycle but that has been increased by almost a million to £6.2 ($7.7 million/€7.3 million).

"The support of UK Sport and the National Lottery has enabled us to realise our potential and build on talent," said Charlie Bethel, chief executive of British Wheelchair Basketball.

"We welcome today's UK Sport funding announcement and acknowledge it as their continued belief and confidence in the medal potential of both the men and women's wheelchair basketball teams."

Para-athletics has also seen a rise as their funding is up to £11.8 million ($14.8 million/€14 million) now instead of £10.8 million ($13.5 million/€12.8 million) last time.

This is a reward for their emphatic display in the Brazilian city earlier this year where they claimed 33 medals including 15 golds.

Para triathlon has enjoyed an increase from £3.1 million ($3.9 million/€3.7 million) to £3.9 million ($4.9 million/€4.6 million).

Para-archery has also received a substantial injection of £1 million ($1.2 million/€1.19 million) after Great Britain won an impressive six medals, including three golds in Rio.

Their funding has risen from £2.4 million ($3 million/€2.8 million) to £3.5 million ($4.4 million/€4.1 million).
