NDP Leader Jack Layton is joining in the election campaign's three-way fight for the suburban vote.

He'll spend his second campaign day in Surrey, B.C., just outside of Vancouver, where he hopes the NDP can gain a seat last won by Conservative Dona Cadman.

The party is also focused on the nearby riding of Newton-North Delta, held by the Tories.

All three parties are doting on the suburbs, partly because suburban populations are growing and changing so quickly that political opinions are in flux and many seats are up for grabs.

The Conservatives have already been to the Toronto suburbs, and Liberal Leader Michael Ignatieff is heading in that direction, too.

In Surrey, Layton will stress the NDP is the most effective choice for voters who want to get rid of the Conservatives -- especially in British Columbia.

He will also highlight the Conservatives' treatment of the Komagatu Maru incident of 1914, when Canada turned away almost 400 people on a boat from India. Many of the passengers died after a confrontation with British soldiers.

The federal government under Stephen Harper apologized for the tragedy, but did not make the apology formal in the House of Commons -- something the NDP will criticize today.

Surrey has a large Sikh population.
