See my last post. They've done well. Watch out for the % of the popular vote for them. They may yet be the third party on the popular vote. The LD vote tends to be concerntrated and restricted to particular consitutencies only and doesn't translate as an even spread across the country. UKIP traditionally was spread across the country much more broadly.
Whoever comes third in the popular vote gets guarenteed airtime on public broadcasters, so this really matters.
