“With regret, I have decided to resign the Conservative Party whip. I am passionate about this constituency and proud to have been the first Conservative parliamentary candidate to be selected via a full open postal primary. This gave every registered voter in the Totnes constituency, regardless of party affiliation, the opportunity to decide which Conservative candidate they would prefer. From the outset, I have made the case for a centrist, moderate and outward looking approach to our politics.

“I assure you that I will continue to take that approach but will now do so as an independent MP. I will carry on working constructively with the many hard-working Conservative councillors across this constituency, for whom I have the greatest respect. My decision is no reflection on them.

“However, at a national level the Conservative Party appears to have abandoned attempts to modernise or to broaden its appeal and has instead become less tolerant and more inward-looking.

“I can no longer remain a member of a party whose leadership has become so driven by the demands of the ERG and the DUP. I do not share their right wing values or those of the UKIP supporters who have been urged to join the Conservative Party via aggressive and well-funded social media campaigns in order to deselect moderate MPs.

“The final straw has been the Government’s mishandling of Brexit. Despite the PM losing her majority, no meaningful attempt was made to reach out to heal the divisions left by the referendum or to seek a cross Party, or national consensus, on the way forward.

“The 48 per cent who voted to remain are marginalised and alienated and many Leave voters have also been left exasperated by the PM’s Deal.

“The trade-offs and compromises in the Withdrawal Agreement and Future Framework mean that the Deal is a long way from the unrealistic promises made during the referendum campaign.

“Brexit has consumed and squandered the energy of Government, Parliament and our political parties. That together with a shift to the right by the Conservatives has undermined efforts to tackle the ‘burning injustices’ the PM pledged to address on entering Downing Street.

“We have reached a precarious moment in our national life. Nothing has divided us like Brexit and we now face the serious prospect of crashing out of the EU in less than 40 days’ time with No Deal and no transition. This would not be a ‘clean Brexit’ as some have chosen to represent it. The serious real-world consequences would harm people not only in this constituency but across the whole of the UK and beyond...”

She added: “The truth is that No Deal Brexit would deal a body blow to our economy, putting jobs and livelihoods at risk as well as crushing the opportunity to reverse austerity.

“Having looked at the evidence of the damage it would inflict, I cannot support a No Deal Brexit and I wholly reject the PM’s false binary choice between that grim option and her own deeply flawed Deal. I have for many weeks said that I would resign the whip if No Deal became the stated policy of the Government but also that I would do so if running down the clock amounted to the same.

“I believe that everyone deserves the right to examine and weigh up the pros and cons of the Deal and to have the final say in a referendum. This would offer the opportunity to confirm Brexit and proceed rapidly with implementation or to remain...”

She added: “The Labour Party has also changed beyond repair. It is now permanently in the grip of the hard left and tainted by its failure to root out anti-Semitism, these are some of the reasons why several of its MPs have already decided that they too must resign the whip.

"I will be sitting alongside them in a new centre grouping of independent MPs who share a common set of values, The Independent Group.“
