Venezuela's new sports minister has hinted that Pastor Maldonado's funding could be at risk.
Maldonado's racing career has been hugely financed by Venezuelan state-owned oil giants PDVSA, but the death of Hugo Chavez in 2013 sparked a period of unrest in the South American country.
Maldonado, who moved from Williams to Lotus at the start of 2014 and has yet to claim a championship point, had a good relationship with Chavez but the new sports minister has indicated that Maldonado's funding could soon run dry.
"I know I'm going to win a lot of enemies," Antonio Alvarez is quoted by Venezuelan publication Ultimas Noticias.
"But there will be not one more dollar for motor racing.
"Venezuelan sport has other priorities, and it would be unfair to use state resources for disciplines that are not in line with the development of the country."
PDVSA features prominently on the Lotus E22 this season courtesy of Maldonado's deal after the company reached a settlement deal with Williams.
