Sainsbury's Bank has denied postponing a £20m marketing blitz aimed at pushing its motor insurance offering.

It was widely rumoured that the campaign would start in early spring.

A Sainsbury's spokesperson said: "We will not be talking about it at all before the launch. Everything is very much on track."

The marketing push will aim for a 20% policy increase this year, from a base of around 150,000 policies.

Walsh Trott Chick Smith and other advertising firms have created the campaign.
