Former UK PM Tony Blair is to receive funding to advise Serbia's Prime Minister Aleksandar Vucic, British media report.

Sixteen years back, Blair was among politicians at the spearhead of the NATO bombing campaigns carried out against Belgrade during the Kosovo War. Vucic himself was Minister of Information of former Yugoslavia at the time.

The United Arab Emirates is apparently funding the deal, the reports of which emerged first in The Guardian, citing Serbian sources. They argue the contract was signed by Blair's private consultancy, Tony Blair Associates.

Vucic himself has been very critical of Blair over the years, and the latest reports have prompted accusations from the opposition.
