The British Red Cross will feature on the shirts of Norwich City players during Saturday's match against Manchester United, thanks to the generosity of the Canaries' main shirt sponsor Aviva.

City's shirts will feature the Red Cross Emergency App hashtag '#ERapp' and Aviva will be donating £1 for every download of the app during a 48-hour period from 11.59pm on Friday night, through until 11.59pm on Sunday – up to a maximum of £10,000.

The app, which launched in the UK in October 2015, is designed to save lives through real time alerts for severe weather and provide emergency advice. It also offers an 'I'm safe' button to tell others you're safe.

The Premier League match kicks off at 12.45pm on Saturday, due to the Canaries' clash with United being screened on BT Sport.

Lindsay Forster, Aviva's customer marketing director, said: 'We're delighted to hand over the shirt sponsorship of Norwich City FC to the British Red Cross and have the Canaries wearing the #ERapp hashtag.

'This is a great opportunity to highlight the fantastic work the Red Cross does and get football fans to download this important app.

'Property damage as a result of bad weather is one of the most traumatic events that any householder or business can face. This trauma places huge responsibilities on us, the insurance industry. Advance warning of bad weather is an effective way to minimise the impact of severe weather – which this app can very much help with.'

The initiative comes shortly before Aviva's eight-season spell as City's main shirt sponsor comes to an end, with a replacement yet to be announced.

The insurance giant will instead become the official community partner of the Canaries, in a new three-year deal aimed at helping local causes.

Chief executive of the British Red Cross, Mike Adamson, added: 'We are very grateful to Aviva and Norwich City Football Club for this fantastic opportunity. I would encourage all football fans to download the #ERapp.

'It provides instant alerts of emergencies and severe weather close to you which could affect you getting to the game. It also gives tips on how to prepare for floods, power cuts and storms.'

The initiative follows other charities benefiting from Aviva giving up their shirt prominence for a match in previous seasons.

In the first three seasons of its sponsorship, from 2008/09, Aviva enabled the Norfolk public to nominate and vote for the charity that they felt should benefit. Winners were The Benjamin Foundation, EACH and the Hamlet Centre.

From 2011/12 to the 2014/15 season the shirt sponsorship was handed over to Aviva's then charity partner The Railway Children and last season it was used to promote the Aviva Community Fund.
