Plans to increase the capacity of Liverpool FC's Anfield stadium to 61,000 have been backed by councillors.
Liverpool City Council's planning committee voted 6-2 to allow the club to add 7,000 seats to the Anfield Road Stand, which currently holds 8,819.
The replacement stand will extend across Anfield Road and near the edge of Stanley Park, drawing an angry response from green campaigners.
Liverpool FC promised to replace all 27 trees that would have to be felled.
Green councillor Anna Key and Labour's Dave Cummings voted against the plan.
The Local Democracy Reporting Service said the council's climate change committee chair, Lena Simic, accused the club of "misleading" the public by not revealing the number of trees until late in the day.
