It's to with how
First Past The Post works in combination with how the constituencies are drawn up.
Labour tend to win most of their seats in urban areas where there can be 5 or 6 candidates for each constituency, thus you usually win the seat with a smaller amount of the vote. While the Tories win most of their seats in rural areas where there are less candidates for each constituency, thus the winning candidate will get a higher percentage of the vote.
Labour will get fewer votes in rural areas and the Tories will get fewer in urban areas.
This is in combination with the fact that there are more people living in each rural constituency (rural areas include small towns), yet there are more constituencies in urban areas.
Support for the Lib Dems on the other hand isn't particularly concentrated in either urban or rural areas, and they tend to do pretty well in most constituencies but not enough to win many of them, thus the Lib Dems are getting a high percentage of the national vote but spread across the whole country, mean while Labour and the Tories get only a slightly higher percentage of the national vote, but it's concentrated in certain areas thus winning them seats.
