Lauri Love is a British national while Assange is a Australian national. Would the nationality of the defendant have an impact on the Westminster Magistrates' Court's decision?
In theory, no. Everyone is equal in the eyes of the law. The nationality of the subject isn't a factor that would have a particular bearing either way. The courts are supposed to look at where it makes sense to try the crime, rather than the nationality of the offender.
In this case, most of the evidence is presumably in the United States so it doesn't make sense for the trial to happen in the United Kingdom, assuming the United Kingdom has the relevant offence too (I haven't looked it up, but I presume it would be breaching the Official Secrets Act or something along those lines).
Obviously, it is more persuasive to have a British national tried at home (especially with comparative legal systems, e.g. the offence exists in both countries) rather than a foreign judicial system. The same cannot be said for a foreign national, especially if the foreign prosecuting authority will have a much stronger case built up than a domestic prosecuting authority could achieve.
