As part of the programme's coverage of 100 constituencies in 100 days, Matthew Price went to find out why voters born overseas want to vote in this General Election.

Chief correspondent Matthew Price has been to Brent North, Brent Central and Hampsted and Kilburn to meet three non-UK born voters.

Brent North and East Ham are two London constituencies where non-British born voters make up more than half of the electorate.

One in ten of the people eligible to vote in next month鈥檚 election were not born in the UK according to a study by the University of Manchester.

Non-UK born includes people who gained British citizenship or who have come from Commonwealth countries - both are eligible to vote in a General Election.

In such a tight election, their impact could be huge.
