Twickenham MP Tania Mathias has confirmed she will be voting for Britain to remain in the EU, just days after Richmond Park MP Zac Goldsmith pledged to vote out.

The borough’s MPs are divided on the subject but Dr Mathias said she did not believe now was the time to risk leaving the group of 28 countries.

She said: “I will be voting for the UK to remain a member of the European Union. I make no attempt to pretend that the EU is perfect, and the referendum will be a choice between two imperfect options.

“Whilst I wish that more could have been achieved, the Prime Minister has negotiated some worthwhile reforms, and I believe that at present we can and should work from within the EU as a proactive and influential member.

“We live in uncertain economic and geopolitical times – I do not believe that now is the time to take the risk of leaving.”

The matter has divided Conservative MPs, with the majority of the cabinet backing the Prime Minister’s calls to remain in the EU.

The referendum takes place on June 23.
