If he's recalled, that will cause another headache. Not just because it's yet another by-election, but the next Conservative candidate for Tamworth is Eddie Hughes, who is moving from Walsall North which won't exist at the next GE.
So either they get a stand-in for a year, or Eddie Hughes stands in Tamworth, then they need another by-election in Walsall North even though the constituency won't exist for much longer.
