The McKenzie Thesis (explain).  Is Britain still a two party

system – was it and is it an accurate model?

In his thesis, McKenzie dedicated 99.6% pages to discussing the Labour and

Lloyd George’s Indian summer.  This hardly suggests they should be written off as minor

and insignificant as in McKenzie’s thesis.  Indeed, had it been proportional today, they

would have got about a 100 of 500 pages.  (Though content should be taken into account

it highlights the inaccuracies today).
