Borse Dubai does not plan currently to sell its London Stock Exchange stake, a senior financial official said, denying a reported $1.5 billion Abu Dhabi offer for Dubai's financial assets.

Ahmed Al Tayer, governor of Borse Dubai part-owner the Dubai International Financial Centre, "emphasized that the Borse Dubai was currently not looking to dispose of its investment in LSE", according to an official statement emailed to Reuters on Monday.

Britain's Sunday Times said in an unattributed report that Abu Dhabi was in talks to buy a 20 per cent stake in the London Stock Exchange held by indebted neighbour Dubai.

"(Tayer) categorically denied media reports that Dubai has received any offers to sell its financial assets," the statement said.

"Al Tayer reiterated that Borse Dubai had successfully completed an early loan repayment and debt restructuring last week."

Exchange operator Nasdaq OMX Group agreed last week to repurchase 11.5 per cent of its outstanding shares from Borse Dubai for $497 million, in a deal which it said would help Borse Dubai meet its debt obligations.

"There is nothing on offer to sell," Al Tayer was earlier quoted as saying by Al Bayan newspaper.

Tayer is also a member of Dubai's Supreme Fiscal Committee, which has had a leading role in managing the emirate's debt crisis.

The LSE stake sale would be part of an Abu Dhabi buyout of Borse Dubai, which owns controlling stakes in local exchanges the Dubai Financial Market and Nasdaq Dubai, the Sunday Times reported, and would follow Borse Dubai's sale of about half of its shares in Nasdaq OMX last week. – Reuters
