Futureway Trust will independently raise money for its National Marriage Week after the Government cut its funding for the project.
The charity had asked for £700,000 to support next year's event, which is run to promote positive attitudes to marriage.
It now plans to launch a fundraising campaign to meet the deficit, which it claims amounts to about 35 per cent of the project cost. The charity hopes to persuade 1,000 people to regularly donate £10 to fund National Marriage Week in 2003.
"We're determined to carry on and we have to find the money,
said Richard Kane, a director at Futureway. "We've spent three years repositioning the event to accommodate everyone's wishes so we've got a lot of work to do."
Kane believes the funding decision was motivated by "political correctness
and said that the charity was led to believe it would receive another grant.
"The decision to cut funding for the project is outrageous. Part of good government is representing the interests of minority groups but it's also supporting the groups that represent the mainstream."
