The Put it to the People March is on March 23, in London, and Delia is among a list of well-known names who are sponsoring coaches to get campaigners there.
More than 160 coaches have already been booked by campaign groups, to get people to the march from across the UK. A train has also been chartered, which will bring more than 500 people to London from the West Country.
The coach sponsored by Delia will be called the East Anglia Express. She also sponsored a coach to the People’s Vote march last October.
