Doctor Who actor Christopher Eccleston has lent his support to a charity picnic that will see a Highgate park turn pink in memory of a schoolgirl who died from cancer.

Mr Eccleston, of Highgate, joined the mother of 17-year-old Alexandra Wylie, Lindsey Wylie, and her former Channing school friends at pan-Asian restaurant Tootoomoo in Crouch End on Tuesday to promote the annual Pinknic in the Park.

The all-pink day of live music, food and games, held on September 6 in Waterlow Park, is in aid of the Alexandra Wylie Tower Foundation, which this year will raise money to fund food parcels and nutrition classes for north London children living in poverty.

The charity was set up in 2011 in memory of Alexandra, known as Allie to friends, who died in 2010 from an incurable form of cancer.

Mr Eccleston, who will judge the picnic’s cake competition, said: “It is horrifying that such high levels of poverty are right on our doorstep and I am pleased to be able to provide support for a programme that is working with local children who are not getting enough food. It is a privilege to work with the charity.”
