With problems in Parliament trying to get consensus on a withdrawal agreement, it seemed the main political parties were edging away from the centre ground. Did this leave a vacuum for a new movement? In 2019, more or less simultaneously, a new party started and a new campaign launched, both supporting a so-called People's Vote on any Brexit deal. The Independent Group - or Change UK, as they came to be known - was not without challenges. Neither was the People's Vote campaign. Eventually, the friction came to be personal. Mark Mardell speaks to the people involved about where it all went wrong. Email: worldatone@bbc.co.uk. Twitter: #BBCWATO

Emotions run high as Theresa May tries to get her Withdrawal Agreement through Parliament, and fails. Not once, not twice but three times.

And while Mrs. May’s government will try again and again if necessary, there will be a cost. Mark Mardell takes a look behind the news reports of the day, into the meeting rooms and corridors of Westminster, and reveals the private tensions of the party’s existential crisis.

After Theresa May's so called Chequers plan failed to impress, the Prime Minister faced another problem within her own party. A group of eurosceptics were gaining interest, members and momentum.

As Mark Mardell follows the twists and turns of Britain's 45 year relationship with the European Union, Mrs May must meet her newest challengers. Email: worldatone@bbc.co.uk. Twitter: #BBCWATO
