    Abstract: The invention relates to a multinuclear metallocene catalyst compound according to Formula (1), wherein Y and Y′ are the same or different and independently selected from the group consisting of C1-20 linear, branched or cyclic hydrocarbyl groups, C1-30 aryl and substituted aryl groups; L and L′ are the same or different and are electron-donating groups independently selected from the elements of Group 15 of the Periodic Table; Q and Q′ are the same or different and independently selected from the group consisting of C1-30 alkylene groups; M″ is a metal selected from Groups 3, 4, 5, 6, 7, 8, 9 and 10 or from lanthanide series elements of the Periodic Table; Z is selected from the group consisting of hydrogen, a halogen and C1-20 hydrocarbyl, C1-20 alkoxy and C1-20 aryloxy groups; z is an integer from 1 to 4; n and n′ are independently 0 or 1, with 1≦(n+n′)≦2; B and B′ are the same or different and each is a metallocene compound, with B being represented by the compound of Formula (2) and B′ being represented by the compound of Formula (3), wherein Si is silicon; R and R′ are the same or different and independently a hydrogen or a C1-20 alkyl or aryl group; D, D′, E and E′ are independently ligand compounds having a cyclopentadienyl skeleton selected from cyclopentadienyl, substituted cyclopentadienyl, indenyl, substituted indenyl, fluorenyl and substituted fluorenyl; M and M′ are the same or different and each is independently selected from the group consisting of scandium, yttrium, lanthanoid series elements, titanium, zirconium, hafnium, vanadium, niobium, and tantalum; X and X′ are the same or different and each is selected from the group consisting of hydrogen, a halogen, a C1-20 hydrocarbyl group, C1-20 alkoxy group; and C1-20 aryloxy group; x and x′ are independently integers from 1 to 3. This invention also relates to a catalyst system comprising said multinuclear metallocene catalyst compound and a co-catalyst, to a method of making the multinuclear metallocene catalyst compound and to a process for the polymerisation and copolymerisation of an olefin in the presence of said catalyst system. The invention relates to a multinuclear metallocene catalyst compound according to Formula 1, wherein: Y and Y′ are the same or different and independently selected from the group consisting of C1-20 linear, branched or cyclic hydrocarbyl groups, C1-30 aryl and substituted aryl groups; L and U are the same or different and are electron-donating groups independently selected from the elements of Group 15 of the Periodic Table; Q and Q′ are the same or different and independently selected from the group consisting of Ci-3o alkylene groups; M″ is a metal selected from Groups 3, 4, 5, 6, 7, 8, 9 and 10 or from lanthanide series elements of the Periodic Table; Z is selected from the group consisting of hydrogen, a halogen and C1-20 hydrocarbyl, C1-20 alkoxy and C1-20 aryloxy groups; z is an integer from 1 to 4; n and n′ are independently 0 or 1, with 1
