Tory donors have said they are in the "fight of their lives" after drawing up a list of over 100 marginal seats to fund with millions of pounds to help Boris Johnson win a snap general election.

Officials working for the Midlands Industrial Council have drawn up the list of key seats with staff working for Darren Mott, the party's director of campaigning in the past seven days.

Donors who abandoned the party under Theresa May are also reported to be coming back to the party due to Boris Johnson's leadership of the party.

Donors represented by the Midlands Industrial Council gave around £5million to the party - both centrally and to individual seats - in the months leading up to the 2017 general election.

At the last election in 2017 the group funded 75 seats directly - 45 of which were won by the Tories.

A large amount could be channelled directly 106 target seats in the likely snap election, The Daily Telegraph has been told.
