Why would this slate "for legal reasons" have to run under a different name? Come on FG you're the expert.
The Political Parties, Elections and Referendums Act 2000 introduced very strict laws regulating registered political parties, as Peter Hain has discovered to his peril

Among a lot of other things, including strict rules on who can and cannot donate money to a registered party, this law also regulates the descriptions under which registered parties can contest elections. The SWP have discovered this recently in the case of by-elections in Leyton and Preston where they had hoped that their members would be able to run as "Respect". These candidates have no description on the ballot paper and are not able to say they are the candidates of any particular party.
In order to run in an election, the "party" has to register with the Electoral Commission. At present the registration of Respect is in limbo - the SWP control the bank account, while Linda Smith of the Renewal grouping is the nominating officer. No candidate can be nominated without the approval of Linda Smith and no candidate can incur election expenses without the SWP's approval. The result is currently stalemate. In addition no other "party" can register with a similar name to an already existing one if they object, as the Socialist Party discovered when it tried to register.
The SWP held secret negotiations to consolidate the split in Respect which included a discussion on future names for the two sides and an electoral pact to prevent either side standing against the other. But the SWP went to the capitalist press to denounce their critics within Respect, and then walked away at the last minute from the negotiations and are trying to pretend that they are the 'real' Respect.
The Renewal side has published its account of the negotiations, but the SWP have never told their membership (yet alone the readership of Socialist Worker) the true story. The SWP are trying to pretend that the SWP candidates in Preston and Leyton are "Respect candidates" but in fact this is probably illegal as it is also an offence under the act to try to pass yourself off as another party (recalling the infamous candidacy of a spoiler who stood as "Literal Democrat" in an attempt to inflict damage on the LibDems - something the Act tried to make illegal).
The SWP's situation was not helped by the fact that they secretly took an almost certainly illegal foreign donation (the infamous Dubai cheque for 10,000 dollars) to pay a debt into Respect's bank account. [While John Rees was responsible for this, three other members of the SWP Central Committee also colluded to hide this donation.] Galloway reported this donation to the Electoral Commission and they are investigating but currently have bigger fish to fry in the form of Peter Hain's similarly illegal donations over which he has been forced to resign. However this issue will not go away for the SWP.
If the SWP had wished their claim for control over Respect nominations to be carried out, they would have to go to the Electoral Commission and argued that their conference on 17th November was valid and that Linda Smith had been removed from the Respect NC and a new Nominating Officer appointed. (Contrary to claims by some in the SWP, who falsely say it would be an expensive legal battle, this actually costs nothing - they just have to write to the Electoral Commission setting out their case for the Respect name)
But the SWP are too scared to go to the Electoral Commission as they know the Commission would want to investigate the claims that the 17th November 'conference' was valid - everyone involved knows that this would not stand up to more than 5 seconds of scrutiny, the invalid student delegates being enough probably on their own, though the failure to ratify the Conference Arrangements Committee and the invalid Tower Hamlets delegation put it beyond doubt.
In fact every step the SWP take on this, including describing the SWP candidates in Preston and Leyton as "Respect candidates", something they have now stopped doing, takes the SWP into deeper difficulties with the Electoral Commission.
So in terms of the forthcoming elections, Lindsey German will be in trouble if she tries to describe herself as "Respect candidate" and incur expenses under that name. The only effective solution is negotiations with Renewal for an agreed seperation. The SWP are still trying to hide the invitability of that from their members and the readers of Socialist Worker.
In terms of the GLA, discussions on standing a wider slate predate the split when it was known that the RMT were interested in contesting. Rees, as usual, made a typical SWP hamfisted intervention and managed to thoroughly piss off the RMT. Galloway wrote an article in the Morning Star back in November supporting a broader slate, and the Respect NC members who support Renewal have asked him to see if the basis for such a left slate exists. The suggestion is that Galloway could head this slate, though it has been made clear that this is not a precondition or agreed yet - just an idea as a basis for discussions.
Any slate contesting the elections would need to register with the Electoral Commission, agree a name with then ... and make sure it did not take any money from Dubai! The SWP used to be registered but withdrew their registration. If they reregister so they can stand German as SWP, they would have to submit their accounts and membership numbers to public scrutiny of course
Expect things to continue to unravel over the next few weeks ...
