It's not utter tosh, it's fact.
The groupings in the EU parliament need to comprise MEPs from (I think) 6 separate EU member states. UKIPs group is called the EEFD and had this Latvian MEP as a member, so the EEFD qualified for the additional funding that is available tobeach recognised group.
then Martin Schulz decided to offer the Latvian MEP an ambassadorial role as EU rep to Kazakhstan, which forced to have to resign from the Eu, meaning the Ukip group no longer had the right mix of MEPs in its group and would be denied funding.
This was just bully boy tactics by Schulz who Faragechas had several run ins with in the last - they are all available to watch on Youtube coverage if the EU parliament business.
The EEFD was able to reform by allowing this latest MEP to join. The views that you described are not his views but those of the leader of his party and it's clear that he has only joined the group as a marriage of convenience that enabled EEFD to continue to receive funding, His views are not the views of UKIP.
It would be easy to feel outraged about this but, they are not his views and in this country and most of Europe ( not Germany) his party leader is free to scores whatever views he wants to as we have freedom of speech. We should also note that he managed to get himself elected o he has a legitimate democratic right to be there.
The EEFD is the only anti EU grouping in Brussels. Schulz would love to see it fold. It would be a very poor day for democracy if views that ran contrary to federalism were Automatically stamped on by bullies like Schulz. So UKIP is holding its nose, using this MEPs presence in the group to pass the qualifying test that enables the EEFD to be funded in the same way as all the other MEP groupings are.
Of course Schulz offered the job go the Latvian knowing that UKIP would either have to join Le Penn or accept this other new member and in full knowledge that the media would then try to smear UKIP. But the public are not stupid and could see right through his tactics.
