Assuming that it is caused by British voters it would, but it may be people pulling their money out of the market in general to wait for the outcome. The other factor is you have an Australian election looming too, so some foreign investors wait for a result before putting their money into a country so they can first gauge what kind of policy their investments will be ruled under. I didn't think Australia would have that issue because both our two parties are fairly central as opposed to some countries, but maybe I'm wrong. All my speculation of course.
