Robert Buckland QC MP has released a statement announcing his backing of the current Prime Minister.
His statement follows the announcement this morning that the required 48 letters calling for a leadership contest had been delivered to Graham Brady, the chair of the 1922 Committee of Tory backbenchers.
A ballot will be held between 6pm and 8pm tonight and a result is expected to be declared by 10pm.
The Member of Parliament for South Swindon said: "I am backing the PM, who deserves support as she works to deliver Brexit and a country with growing employment, a growing economy and great investment in our valued public services like the NHS."
Theresa May has vowed to contest the vote of confidence in her premiership, warning that her removal as prime minister and Conservative party leader will delay or possibly postpone the UK’s exit from the EU.
She has today to convince 158 MPs to support her in the vote and will enter her final plea at the 1922 Committee meeting at 5.30pm. So far 107 MPs have come forward to say that they will support her.
If she wins, MPs cannot call another vote for 12 months.
If she stands down or loses the contest, the next part of the process – when Tory MPs cut down the contenders to a shortlist of two – could be completed relatively quickly, within 10 days.
Conservative party members would then be asked to choose between the final two candidates.
