The first speech from Rishi Sunak in which took place on the 11th June 2015 as part of the European Union (Finance) Bill which he did not refer to at all and he spoke about his background and ended with this statement

I believe in a compassionate Britain that provides opportunity and values freedom. I hope I can play a small part in ensuring that our great nation continues to hold to those enduring values.

He then went on to ask this question on the 16th June 2015 to Damien Hinds

Will my hon. Friend tell my constituents what this Government will continue to do to cut the costs of childcare for hard-working families?

and then a few days later on 24th June 2015 he spoke to the Prime Minister of that period, David Cameron

As the Prime Minister mentioned, access to high-quality broadband is essential in today’s digital economy. Will my right hon. Friend tell us about his plans to get broadband to my rural constituents and those in rural areas across the country?

A few times after he spoke again he asked this written question which was responded on the 7th July 2015 by Alistair Burt.

To ask the Secretary of State for Health, what progress the Government has made on integrating and improving care provided outside of hospitals.

Now to be clear, he has never spoken in Parliament about the value of staying in the European Union but one of his first comments after the referendum ended with these suggestions on the 6th September 2016.

As we contemplate leaving the European Union, it will be vital that Britain’s economy remains dynamic, open and competitive to attract the investment we need and maximise the opportunities afforded to us. The clauses relating to capital gains tax and carried interest will ensure that the UK does exactly that, and I will support them later today.
