After the May 1978 elections (i.e. the last round of elections before they won the general election) the Conservatives had 49.6% of councillors.
After May 1996 (i.e. the last round of elections before they won the general election) Labour had 48.1% of councillors.
The Conservatives had 38.6% after last May’s elections, so to get up to 48.1% would require net gains of over 2,000 councillors this May (even allowing for by-election gains in the interim).
Yet although the Conservatives talk about wanting to win the next general election, this is way beyond what I can find any Conservative talking about. Hmmm……
