YORK insurance giant Aviva says it considers the EU referendum results will have 'no significant operational impact' on the company.

It said in a statement it had reached this conclusion after conducting extensive analysis of the possible implications of a leave vote.

Its comments came as York Central MP Rachael Maskell has spoken of her concerns for such local companies, saying: "We have heard Aviva talk about the uncertainties should there be a decision to leave."

Aviva said its operations in the UK and its other subsidiaries in the EU were well capitalised and continued to trade as normal. "Aviva continues to be supervised by the PRA/FCA as lead regulator and Aviva’s European subsidiaries are incorporated and regulated locally and principally trade in their local market," it said.

The statement said Aviva had one of the strongest and most resilient balance sheets in the UK insurance sector, with 'low sensitivity to market stress,' and over the last four years it had tripled its economic capital surplus.

"Aviva will continue to monitor the technical implications of the vote to leave, which will only be resolved after several years of negotiating a new relationship between the UK and the EU."
