Local election results will give clue to national poll - BBC News
Local election results don't translate directly to the general election - but they are a significant barometer.
These elections are a complicated set of local contests, some old, some new, some electing an individual to a position of great power, most, individual races in wards that make up only a few streets, for councillors who then group together to run our towns and cities.

So as the results come in, from the early hours of Friday morning right through the day, what are we looking for?

First, these are important elections in their own right, and the results make a big difference to decisions that are made on our behalves all round the country.

Pay attention, therefore, to how the Conservative and Labour fight shapes up in areas like Nottinghamshire, or Derbyshire.

And the Lib Dems are crossing their fingers for signs of a comeback.

To get their activists gingered up for the General Election they need signs of decent gains around the country.

The elections of new metro mayors will also be big headlines - particularly in Birmingham where the two big parties are both desperate to win.

It will be a long, and complicated day, and don't forget the caveats with which these results need to be coupled.

But the most important test of all will be whether Labour loses or gains seats in England, in parts of the country where the General Election will really be decided.

If they lose seats in England, that is a depressing indicator for any political party that wants to be seen to be on track for government
