Onus on Liberal Democrats to prove that coalition politics work

Following an indecisive outcome to Thursday's general Election in the UK, talks continue on the potential for the Conservatives and Liberal Democrats to work together in some way to deliver successful government.

It is obvious that differences exist between the two parties on many of their policies and their core ideologies.  However, it seems to me that the onus is primarily on the LIberal Democrats to demonstrate that different parties can work together effectively "in the national interest". 

It is presumed that the main 'sticking point' in the negotiations is likely to centre on electoral reform, with the Lib Dems wedded to full-blown proportional representation and the Conservatives remaining steadfastly in favour of the current, "first past the post" system.  One result of the former arrangement would be perpetual coalition or minority governments. And so, it is in the interest of the Lib Dems to show that 'strong' (in the sense of credible and workable) government can be forged by different - and otherwise competing - parties working together in partnership.
