Mulholland, who has written in his capacity as chairman of the All-Party Parliamentary Save the Pub Group, demanded the move in a letter to IFBB chairman Paul Wells.
The MP claims this is necessary as Young’s has sold its 40% share in Wells & Young’s Brewing Company, the Young family no longer plays a leading role and it has been involved in “contentious pub sales to developers”, such as the Castle in Battersea, south London.
Mulholland said: “The sad reality is that, since shedding its famous brewing arm, Young’s is just another property-dealing pub company, cashing in valuable and wanted pubs for redevelopment.
“Young’s is neither family-run, nor a brewer, and continued membership of the IFBB would be both misleading and also damaging to the reputation of the organisation and indeed other family brewers, true family brewers that continue to operate with integrity and support their tenants and pubs.”
However, the IFBB’s Wells has refuted the claims made by the Leeds North-West MP.
He said: “The IFBB is satisfied Young’s has an operating and financial interest in Young’s brands, by virtue of its retained ownership of those brands, which are predominantly sold throughout its estate of 240 pubs.
“The Young family also maintains a substantial shareholding within the company and a family member holds an executive director position on the board.”
Young’s refused to comment on the claims.
