If your timing is right and you don't mind some time in line, it is possible to visit British Parliament for free. There is a public queue (line) outside the St. Stephens entrance. About.com's London Travel Guide advises arriving about 1 p.m. on the days Parliament is in session to avoid the longest wait times. The House of Commons Information Office can provide updated information for what might be happening on the morning or afternoon of your London layover.
