Tim Bell calls general election TV debates 'pointless'‏

I think he may have a point. If we're going to do it at all then the whole cabinet and their shadows should be involved. We don't have a presidential system, we have parties. If people want a presidential system (I would be in favour if the president replaced the monarch) then that's a whole other issue.
As it is, we are far too focused on one individual as leader. Hardly surprising if they then take all the power for themselves is it?
