Formula E will return to Battersea Park this summer and children under 16 will be eligible for free tickets.

The controversial electric car racing event will be held in the park for the last time on July 2 and 3, after the organisers opened discussions to have a street race through London next year.

London's Sam Bird will be keen to repeat his success after last summer's event, and Sebastien Buemi, Nelson Piquet Jr, and Bruno Senna will also be on the grid.

The two day event is the Formula E championship finale after round in Mexico City, Berlin and Paris.

The series is the world's first fully electric racing series, and started in Beijing in September 2014 before the finals came to London last summer.

In the championship, nine teams, each with two drivers go head-to-head in 11 races in 10 cities around the world.

The two day event will run with the support of 245 volunteers who will help with spectators with directions, accreditation and other operational duties.

Volunteers are working through the Mayor of London's Team London scheme, created for the 2010 Olympic games.

The London event director Oli McCrudden said: "We have been delighted with the interest and commitment demonstrated by the 245 people who will be a part of our team in London.

"Team London has done an excellent job in recruiting so many passionate and enthusiastic workers, who will help ensure that the fans who come down to Battersea have an amazing time."

This year, children under-16 will be eligible for free tickets for the event.

Formula E chief executive Alejandro Agag said: "One of the goals of Formula E is to inspire a new generation of motorsport fans.

"The fan base for traditional motor racing has been steadily getting older and this had to be addressed if the sport is to have a future.

"Through embracing digital and social media, and our involvement in computer games eSports, Formula E has successfully reached out to younger fans, which made offering them entry to our season finale the next logical step."

Anyone with a ticket for an under-16 will be contacted and offered a refund before the event.

The event has proved controversial with Battersea residents, and legal action was threatened by a group led by author Jamie Jackson, who said the park was the wrong London location for Formula E.

In May, it was announced that despite there being at least one more summer in Formula E's contract with Wandsworth Council, the event would not return to Battersea in 2017, as discussions about a street race past London's landmarks had been opened.

There are three ticketing options, offering various access to viewing platforms and the evillage, with activities for families.
