Qatar yet to dissuss raising Barclays stake -source

DUBAI, Sept 17 (Reuters) - Qatar Investment Authority has yet to discuss raising its stake in Barclays Plc (BARC.L) after the British bank agreed to pay $1.75 billion for some of Lehman Brothers Holdings Plc LEH.P, a person close to the fund said.

Barclays said on Wednesday some of its shareholders had expressed interest in increasing their stakes in the bank as part of their support for the deal, and its board expects those discussions to lead to a subscription of at least $1 billion of additional equity.

A person close to the Qatar Investment Authority said the issue "had not come up for discussion yet."

Qatari investors took about an 8 percent stake in Barclays in June.
