THE owners of the birthplace of Scotland's most famous explorer say they remain optimistic despite warnings that running cost funding could be withdrawn if multi-million pound renovations do not go ahead.

The David Livingstone Trust denied there is a "gun to our head" after the National Trust for Scotland (NTS) warned financial support for the David Livingstone Centre in Blantyre, South Lanarkshire, might have to be blocked if plans to transform the attraction did not materialise.

It is estimated £12 million is required to refurbish and repair the birthplace museum of his life and work which is housed in Shuttle Row, a tenement which the Livingstone shared with 23 other families.

Ian Livingstone, chairman of the David Livingstone Trust said they were positive over providing a viable future for the centre with the NTS.

He said a development plan was being finalised over the next few months and would be used to obtain the necessary funding from the likes of the Scottish Government and Heritage Lottery Fund.

"We want to get the centre to a position where it will host things that will attract families to go there and go back," he said.

"We are not looking at a doomsday scenario, we are looking at what we feel will be a viable future for it."

The NTS which manages the property has warned it cannot keep funding the centre as it stands because it is running at a financial loss.

The centre which attracts an estimated 25,000 visitors a year was given a 12-month financial lifeline by the NTS and South Lanarkshire Council, which helps fund costs to run the centre and 20-acre estate.

A spokeswoman for the trust said: "The trust fully recognises the importance of the centre and its critical place in our heritage, which is why we are playing such an active role in seeking out a long-term solution.

"Major investment is needed to make that happen so we are carefully exploring external funding options."
