Protestant victims campaigner Willie Frazer, who threatened to picket First Minister Ian Paisley's house, was today meeting the DUP to discuss the multi-million dollar compensation case against Libya.
Mr Frazer, who last week delivered a protest letter to Deputy First Minister Martin McGuinness' home in Londonderry, is also to meet Secretary of State Shaun Woodward with DUP MP Jeffrey Donaldson over the issue.
Mr Woodward will be asked to support efforts for opening diplomatic channels to reach a Lockerbie-style compensation settlement with Colonel Gaddafi.
The DUP today reiterated its intention to press for UK diplomatic support for the class action, involving around 170 people, including some from Northern Ireland, which was filed in Washington last year.
Mr Donaldson said: "I have been working with Willie on this issue for some time and can confirm the DUP's support for the FAIR (Families Acting for Innocent Relatives) campaign.
"The legal case is ongoing. Lawyers in New York are preparing the case to present to the International Court."
The Lagan Valley MP said he believed his party leader would be involved in the long-running controversy. "We are now seeking the support of the United Kingdom Government in applying diplomatic pressure on Libya because Gaddafi must recognise the pain and suffering he caused by proxy, through his connection with the IRA," he said.
"The UK and US governments also have to recognise their responsibility because it was as a direct result of Margaret Thatcher's support for the Americans in bombing Tripoli that Gaddafi turned his attentions to Northern Ireland again."
Gaddafi said he renewed support for the Provisionals in 1986 after Britain allowed its bases to be used for American jets to bomb Tripoli.
