A war of words has broken out between two Birmingham organisations aimed at getting more ethnic minority people into work.
The dispute, which could end in a costly court battle, centres around claims that a trademarked name has been infringed, resulting in potential clients being poached.
Birmingham Professional DiverCity says the name adopted by a newly-established rival - Diverse City Services - is too close to its own.
It claims people calling directory inquiries asking to be put through to its staff are getting directed to the other body instead.
The publicly-funded organ-isation, which places black and Asian people in professional jobs, has sent a solicitor's letter to its rival threatening court proceedings.
Aaron Reid, deputy director of DiverCity, based in Newhall Street, said: "We are aware of an organisation called Diverse City Services. We are concerned that the use of the name has caused confusion for a number of our clients and contacts.
"We have consulted lawyers about it and are currently awaiting a response from Diverse City Services."
Mr Reid added: "We hope we can come to an agreement. We are keen to enter into a formal partnership with them and I h ope we can resolve it amicably."
Diverse City Services, based on Suffolk Street, was set up six months ago by Doreen Osbourne and Christine Hemming, wife of Birmingham Liberal Democrat MP John Hemming.
Ms Osbourne remained defiant last night, claiming the two organisations were different enough not to cause conflict.
"They are a large organisation that has got funding from Advantage West Midlands and the Learning and Skills Council," she said.
"We are two black women who started up an agency in a tiny office and they seem to find us a threat.
"They have threatened to close us down because of the name."
Ms Osbourne said they had offered to change their name and letterheads if financial help from DiverCity was provided, but their offer was refused.
"We have made reasonable offers to them to change it so we are in a stalemate situation," she said.
A letter from Birmingham-based solicitors Shoosmiths states: "Our client has built up a substantial reputation and goodwill in the name of Birmingham Professional DiverCity, often referred to as simply 'DiverCity'.
"We have advised our client that your use of a nearly identical name in relation to your services gives our client grounds to bring proceedings".
The letter gives a deadline of Thursday to respond, after which it threatens obtaining an injunction against Diverse City Services.
