PARIS, July 1 (Reuters) - French Green party lawmakers have announced plans to file a no-confidence motion against the government over its handling of a severe ‌heatwave in late June, as the country braces for a third possible bout ‌of extreme temperatures next week.

It was not immediately clear if the motion would be put forward this week or ​early next week.

• When asked about the motion, government spokesperson Maud Bregeon said on Wednesday: "Obviously, it's going to be filed. It is a political manoeuvre." "There is a government managing the crisis and there are political forces fueling the crisis by introducing the motion," Bregeon told reporters ‌after a meeting of the French ⁠Cabinet.

• The bid to topple Prime Minister Sebastien Lecornu’s minority government is unlikely to succeed without the backing of other opposition parties, including ⁠the far-right National Rally or the Socialists. The Socialists have not supported any of the no-confidence motions filed against Lecornu since he took office last year.

• Cyrielle Chatelain, who leads the Greens ​in the ​National Assembly, said on Tuesday the motion would ​be filed to protest at the ‌government's "lack of preparedness not only for the heatwave we have just experienced, but especially for the one that is coming."

• Though temperatures have started to drop from record-high levels, they are still around 30 degrees Celsius (86°F) in much of the country and are expected to rise again at the weekend, national weather forecaster Meteo-France has said.

• French PM Lecornu said ‌on Monday he was keeping the country's health ​emergency response plan, ORSAN, at its highest level for ​the coming days in view of "a ​possible recurrence of a heatwave episode".

• France has recorded at least 1,000 ‌excess deaths during the blistering heatwave that ​has swept Europe since ​June 20, the public health agency said on Sunday, warning that the true figure was likely to be higher.

• During question time at the National Assembly on ​Tuesday, Chatelain said the government ‌bore some responsibility for the deaths during the heatwave. PM Lecornu angrily challenged ​a figure of 10,000 deaths recently floated by some Green MPs as "scandalous" ​and "undignified".
