LONDON goes to the polls next Thursday to elect a mayor and a Greater London Assembly.

Voters will be asked to make four crosses on May 4.

They will vote once for their first choice for mayor, and again for their second preference for mayor.

If no candidate wins more than half the first choices, then the second preferences will come into play in determining the winner.

The third vote is for a member to represent the Enfield and Haringey constituency on the Greater London Authority.

The winner will be selected using the first-past-the-post system, as in general elections.

However voters get a chance to put a fourth and final cross on their ballot papers.

The GLA will be made up of 25 members ? 14 constituency members and 11 London-wide members.

The London-wide members will be chosen by proportional representation to ensure that the share of seats a party gets in the assembly reflects the votes cast for it.

But in the London-wide section, voters choose a PARTY, not an individual candidate.

The winning candidates will be selected from lists drawn up by each of the parties.

The bigger the vote a party has, the more candidates on its list will make it into the assembly.

Polling cards should have been delivered to all registered voters.

Voting is being spread out over several days.

Haringey residents can vote today and tomorrow at the One Stop Shop, Safeway Arcade, Wood Green, from 7am to 9pm.

There will also be London-wide electronic counting systems in place for the first time in a bid to speed up the counting process.

The count will be held at the Lee Valley Centre in Picketts Lock, Edmonton.
