London (Reuters): The British government will not appeal a court ruling on its plans to tackle air pollution and will meet a deadline for May 9 to detail its efforts to improve air quality, Prime Minister Theresa May's spokesman said on Tuesday.

The government had sought to extend an April 24 deadline to submit its plan to improve air quality and comply with EU nitrogen dioxide limits, but a court ordered a draft plan to be submitted by May 9 and a full report by July 31.

"We have looked at the judgment from last week and we will not be appealing," the spokesman told reporters.

"The court deadline was I believe the 9th of May and we will be meeting that deadline."
