Douglas Carswell will return to his Clacton constituency today flanked by Ukip leader Nigel Farage as the pair plan a completely unexpected by-election campaign.
They are due to visit the seat after Mr Carswell's bombshell decision to switch parties and quit the Commons to re-stand under the Ukip banner.
The date for the by-election is yet to be set but is likely to be held within weeks. Parliamentary rules require an election between 21 and 27 days after a writ is moved to fill the vacancy.
