The choice of the Tor Vergata area, home to the university of the same name, for the location of the Olympic Village had received the green light from environmental organisations Greenpeace, the World Wide Fund for Nature, Lipu, Italia Nostra and Legambiente earlier this month.

It was claimed the decision to build in the area would help to "restore the abandoned Vele di Calatrava structures, bring the subway to an area of Rome that has a great need for it and boost plans to use existing University student dormitories and hospital facilities".

The backing of the environmental organisations for the capital’s bid was viewed as an important step in trying to convince Raggic, an Olympic skeptic, to support Rome 2024’s efforts.

Raggi has been a leading critic of Rome’s attempts at bringing the Games to the city for the first time in 64 years, and any opposition from her towards Tor Vergata would create another stumbling block.

Giovanni Malagò, the President of the Italian National Olympic Committee (CONI), has claimed that Rome 2024 are open to changing the location of the Village, however.

His view was backed by Rome 2024 bid leader Luca de Montezemolo, who stated that despite the backing of the environmental organisations, they would still be willing to alter their proposals.

"We indicated that location in agreement with environmentalists," he told the Italian news agency ANSA.

"We took several factors into account, including the distance between facilities and their possible use after the Olympics on a university campus.

"If we want to change the location, that's fine.

"We must convince 85 International Olympic Committee members to choose Rome over Los Angeles and Paris."

Raggi, a 37-year-old lawyer and Five-Star Movement politician, says she will hold talks with Italian Prime Minister Matteo Renzi, a keen supporter of the bid, “straight after the summer”.

Renzi has frequently urged Raggi to withdraw her opposition and it is difficult to see how things can progress without her support.

She reiterated her view, earlier this week, that she will look to solve "core problems" in the city such as potholes and transport before “evaluating the extraordinary” - a reference to the Games.

She indicated that a decision on whether Rome should press ahead with its bid will be made in October.

Rome 2024 remain hopeful their bid could retain the support of the new city authorities following a meeting earlier this month.

A delegation including bid vice-president Luca Pancalli and Malagò met with the city's deputy mayor Daniel Frongia, who has special responsibility for sport, as well as Rome's Five-Star Movement leader Paolo Ferrara.

Frongia claimed afterwards that the city was “open to dialogue”.

Paris and Los Angeles are also bidding for the 2024 Olympic and Paralympic Games along with Budapest, which wasn't mentioned in de Montezemolo's quote to ANSA.

The International Olympic Committee is due to elect its chosen host at its Session in Lima in September 2017.
