The Olympic torch is to feature on EastEnders, be carried by the one-time captain of the Starship Enterprise, and visit the hallowed lawns of Wimbledon.

In a star-studded day for the flame, Sir Patrick Stewart, who played Capt Jean-Luc Picard in Star Trek, will be boldly bearing the torch in a school in Croydon, south London, at around lunchtime.

Later, it will be carried around the All England Tennis Club at Wimbledon by Venus Williams and Andy Murray, who so recently endured a heartbreaking final defeat to Roger Federer on Centre Court.

In the evening, the symbolic flame will be taken into the homes of millions as EastEnder Billy Mitchell carries the torch through fictional Walford, E20. After weeks of planning, the soap will welcome the torch at its home in Elstree, Herts, where it will then be passed to Billy, who will continue its journey past some of the most famous landmarks, including The Queen Vic, in a live special.

Also carrying the torch will be Doreen Lawrence, mother of murdered black teenager Stephen Lawrence. The campaigner will take it to the learning centre she set up in her son's memory in Deptford, south-east London.

The latest leg of the relay is sure to ramp up excitement for the Games but the identity of the final torchbearer, who will light the cauldron in the Olympic stadium on Friday, remains shrouded in mystery.

But the lid will be lifted on one of the secrets surrounding the ceremony when Team GB announce who will bear the Union Flag during the Danny Boyle-directed opening spectacular.

On Sunday, the torch soared to a high point in the 70-relay when it was held aloft on the London Eye. Amelia Hempleman-Adams, who became the youngest person to ski to the South Pole when aged just 16, grinned from ear to ear as she held the flame on top of a capsule on board the giant wheel.

And on Sunday night, former heavyweight boxing world champion Lennox Lewis was cheered by thousands of people who gathered for an evening celebration in Danson park, Bexley, which saw a performance from pop duo Rizzle Kicks.

Lewis, who won an Olympic gold medal in Seoul in 1988, raised the torch high above his head as he ran towards a cauldron before lighting it with his torch, telling the crowds it was an "amazing honour".
