The two officials are scheduled to discuss plans to extend a gas pipeline that will run from Azerbaijan to Puglia in Southern Italy.
The issue of the TAP has divided the ruling Italian coalition of the Five Star Movement (M5S) and Salvini's League. In June, Guglielmo Picchi, who is also a foreign policy adviser to Italian Deputy Prime Minister and Lega Party leader Matteo Salvini, told Sputnik:
"The TAP is an important strategic infrastructure for Italy and Europe: it is our intention to put it in place, obviously in consideration of every possible fallout it could have on the environment."
Environmental protection activists, however, argue that Puglia, which has two UNESCO world heritage sites, will suffer if the pipeline project goes through.
Given Mr. Blair's anti-populism stance and position as head of the Institute for Global Change, a movement dedicated to combating populism and its causes — he might be an unlikely candidate to convince populist Mr. Salvini in talks.
The TAP is one of the sections of the Southern Gas Corridor, along with the South Caucasus Pipeline (SCP) and Trans-Anatolian Pipeline (TANAP). It is expected to bring 10 billion cubic meters of gas from the Azerbaijan's Shah Deniz Stage 2 gas field to Europe per year. The pipeline will be 878 kilometers (545 miles) long.
