THE Jubilee Line is completely suspended this weekend for improvement work.

The Tube line closure may cause problems for concert-goers heading to Wembley Stadium for Saturday's U2 concert.

The improvement work is part of a long-term plan to upgrade the whole Jubilee Line ahead of the Olympics in 2012.

Passengers can use the Metropolitan and Bakerloo Lines to get to Wembley, or use replacement bus services.
